What is Glaucoma?

Glaucoma is high pressure in the eye. This pushes on to the optic nerve fibres leading to their destruction. These nerve fibers are responsible for vision. Loosing them leads to defects in the field of vision. The most common cause for the rise in pressure inside the eye is blockage of the drainage channel. With nowhere to exit the fund builds up inside the eye. This is like a blocked drain leading to overflow of the basin.

Glaucoma can be followed for progression. It can be by subjective test like visual field. We have one of the latest windows based machine to help you do this test easily. This latest generation of machine can also track changes in changes in your visual field.

How does IStent for glaucoma surgery work?

You may have heard of stents for the heart. Like those stents Istent is placed to overcome the blockage by providing an alternate path for flow of the liquid from the eye. Currently this FDA approved device is to be used at time of cataract surgery.A surgical gonioscope is deployed to visualize the angle of the eye. The titanium stent is placed very carefully in the anterior trabecular meshwork. There is no pain involved and no one can see it. Total internal reflection prevents it to be see other than with a gonioscope. It can even be performed with Pi in Eye.

Cataract Surgery After LASIK

Cataract Surgery After LASIK

Cataract Surgery After LASIK eye procedure requires special expertise. There are many important points to think about. Lets divide the factors to consider into three groups. Calculations before Cataract eye procedure, Techniques during the cataract surgery and management after the cataract eye surgery.

Calculations before Cataract eye procedure

Its very important get certain data before proceeding with cataract eye surgery.

  1. Length of the eye: This can be measure by ultrasound or laser. Laser detection with Iol Master or Lenstar.
  2. Curvature of the cornea: This is where the fun and headaches begin. Lasik eye surgery changes the relationship between the front curvature of the cornea and its back curvature.
  3. Power of the cornea: Detecting the true power of the Cornea is the holy grail of determing Iol power for emmetropia in patients undergoing cataract surgery after lasik eye surgeries.
  4. Distance between cornea and the lens: Also known as anterior chamber depth.

Techniques during the cataract surgery

The style of removing the cataract and inserting the new lens.

  1.  Laser Or Manual Cataract Surgery: Will laser make corneal incisions too close to the flap?
  2. Type of Implant – Monofocal or PIE: We need to to asses the optical zone on Corneal topography. Corneal pachymetry map needs to be evaluated.
  3. Which PIE will work best for that eye: Crystalens or Tecnis multifocal could be an option. Some patients have loved the Restor.

 Management after the cataract eye surgery

Correcting the residual refractive errors by laser or limbs relaxing incisions may be required. Aggressive management of dry eyes is essesntial.

Cataract Surgery after Lasik eye surgery

LASIK eye surgery involves reshaping your cornea to correct a wide range of refractive errors – providing you with clear, sharp vision that either eliminates or greatly reduces your dependence on glasses and contact lenses. However, LASIK cannot prevent the development of cataracts later in life, since cataracts are a problem with the eye’s lens, not the cornea.

Because LASIK involves reshaping your cornea, you will need to consult with an experienced eye surgeon before undergoing cataract surgery in the future. Once your cornea is reshaped during LASIK, your cataract surgeon will need to perform a careful examination in order to determine the correct degree of power needed for your intraocular lens (IOL) – the artificial lens that is implanted during cataract surgery.

If an inexperienced surgeon takes the incorrect measurements, your vision may become out of focus following cataract surgery, requiring additional procedures to restore ideal vision. Thankfully, Dr. Khanna’s extensive experience with both LASIK and cataract surgery has equipped him with the skill necessary to accurately evaluate the changes in your eyes caused by LASIK surgery, ensuring the best possible vision with your IOL after cataract surgery. After removing the cataract, Dr. Khanna will perform a manifest refraction to determine the appropriate lens power for the IOL. Based on this information, the correct IOL will be implanted. You can read more about this topic in the bestseller book on cataract surgery.

If you have further questions about LASIK or cataract surgery, please contact The Khanna Institute today or call (877) 254-2662 to schedule an appointment with board-certified Beverly Hills LASIK surgeon Dr. Rajesh Khanna. We serve patients in Beverly Hills, Westlake Village, and surrounding areas of Los Angeles.

Windmill Technique – Latest Cataract Surgery Method

Windmill Technique – Latest Cataract Surgery Method

We know that phakoemusification or cataract surgery using ultrasound is constantly evolving. This is done with an eye towards safety. as cataract surgery has evolved it has decreased occurrence of problems. The incidence of infections has been the most important chapter in modern cataract surgery. Decrease in breaking of the posterior capsule of the lens bad has been a feather in the cap of top cataract surgeons.

Windmill technique: This new technique has been published in the Journal of Cataract and Refractive Surgery in 2014. The authors display a new safer method of lens removal using minimal energy. They employed an Infiniti Ozil apparatus system. Instead of first breaking the centre part of the lens into multiple pieces they go after the soft part first. They churn the softer outer part utilizing oscillations of hand piece. Than they liquify the central hard part of the lens. This avoids the sound energy traditionally used. It also has the advantage of working away from the cornea. Windmill Technique – Latest Cataract Surgery Method, also prevents small pieces of lens from flying around and keeps a safe distance from the posterior capsule.

Bifocal Implants – A Breakthrough from Monofocal Lenses


Bifocal Implants – A Breakthrough from Monofocal Lenses

Cataract surgery done these days is good and safe. The surgery can even be finished in less than 20 minutes on top of a very short recovery period requirement. This attracts most people with cataract to have cataract surgery. Unfortunately, despite these advancements, a major downturn is that the treatment by insurance only uses monofocal implants, which means that only a single point can be focused. If this is the case, the patient will still be required to use correction glasses to help make their vision a lot clearer.

Bifocal Implants

Monofocal implants were used before in making clearer vision for patients, but by the last few decades, a new implant known as bifocal was introduced. This means that the lenses are multifunctional, which also indicates that the patient can focus different distances already and do all things independently after the treatment. Infact I inserted bifocal implants in the early nineteen nineties. Thats over two decades of experience implanting sight improving intraocular implants. These bifocal implants were manufactured for the first time by the company Shah and Shah.

The bifocal implants lenses are beneficial for people who do not want to depend on glasses and have reached an age over 45. This is different from the LASIK surgery because the latter does not require implants. Lasik eye surgery does not require a sterile surgical suite; but instead performed in a clean laser suite

There are three different types of FDA approved bifocal implants lenses and they are called Tecnis, Restor, and Crystalens. You must know what these types of lenses are as well as what their differences are before agreeing on what type of surgery has to be done for you. The discussion must be done by the surgeon who will do you the surgery. A good source of information for these bifocal implant lenses is this book on cataract surgery. You must not rely solely on the advertisements you can see in the media since some aspects might not be discussed thoroughly.

Your decision in choosing what type of lens to use for your cataract procedure might then be affected by the cost associated with the implant types. This is because only few insurance providers cover these types of services and lenses, so therefore you may need to look at your finances and available options of monthly payments.. At our Cataract eye center, of Thousand Oaks, we offer patient lens implants based on what people with fixed income can afford and what they desire in regard to vision correction. Out Top Cataract Surgeon makes sure to offer the most appropriate up to date technology in cataract surgery and provides an array of lens options for each patient.

Instances That Suggests You to Have Cataracts

Instances That Suggests You to Have Cataracts

Having an eyesight problem like cataract can surely be a hassle, as it will not allow you to do more things that require clear vision. If you want to get back your life before you have cataract, you should look for a surgeon and make an appointment for cataract removal treatment immediately. You must not wait until it gets worse. If you are not sure yet whether you already need treatment, here are some of the Instances That Suggests You to Have Cataracts.

Eyesight Changes Too Often

Maybe it is time for you to stop relying on eyeglasses, as it will just cost you a lot of hassle over time. It is best to look for a doctor and have a cataract surgery immediately. Inconsistent eyeglass grade necessity is a symptom of cataract.

Poor Overall Vision

You must understand that having an unclear vision does not immediately suggest you will need to have cataract surgery since some individuals might just need correction glasses. However, if you notice that even with using eyeglasses you still cannot see clearly, especially at night, you must see a doctor immediately. Not all people show the same cataract symptoms, so you must be aware of what is happening with your own eyesight.

The Color You See Fades

You must take note the at times individuals can see color differently from other individuals. Commonly, doctors perform a test to determine this by examining two patients. The doctor will show a image and if you cannot state what the real color is, you may need to be subjected to cataract removal.

Double Vision

Cataracts are notorious in causing multiple images. This may lead to difficulty in perceiving the right image. Seeing double of an object is termed as diplopia. Cataracts cause monocular diplopia – that is when one eye is covered the other still sees two objects

Difficulty driving at night

When driving at night cataracts can cause difficulty causing glare, haloes, and decreased overall vision. If you have difficulty with light at night or see glare and haloes this may be cause for a cataract removal. Glare and Haloes may not be solely due to cataracts so a exam with an ophthalmologist is required to find the correct cause.

Extra light to Read (Forget those Menus)

Cataracts can cut off incoming light into the eye, preventing the light from reaching the back of the eye. Therefore you may notice you require extra light when reading your favorite book in bed or menus in restaurants.

Having all or any of the symptoms above might alarm you, as those are the symptoms of patients who need cataract removal. Hence, do not be hesitant in calling up an appointment with your doctor as early as possible.

Possible Complications of Cataract Surgery

Possible Complications of Cataract Surgery

By Rajesh Khanna MD

a member of American Society of Cataract and Refractive Surgery

Cataract surgery is a type of operation that has been around for decades now. This is deemed as one of the safest surgeries there is. The success rate of cataract surgery is at 98% as per the American Society of Cataract and Refractive Surgery . However, no matter how safe a procedure is, possible cases of complications of Cataract Surgery still arise. Though these complications may be of minor ones and can be easily corrected, knowing them would still be best so you may prepare in case they happen.

Possible Complications of Cataract Surgery

  • Infection and Bleeding – these two are common complications that can happen in surgeries and cataract surgery is no exception to this complication.
  • Posterior Capsule Opacity – this is one of the most common complications of cataract surgery. This side effect happens when the lens capsule protecting the eye lens grows cells from the outer layer of the cornea onto the capsule. This will then result into a hazy vision. Nevertheless, a laser treatment procedure can correct this. This complication may happen in 20% of cataract surgery patients.
  • Double Vision – Double vision happens when the implanted intraocular lens gets out of place or dislocated. This can be treated by your eye surgeon by re-positioning your dislocated lens. If the dislocation happens again, this can be corrected by sewing the lens in place.

Other Cataract Surgery Complications – other complications following a cataract surgery may include, but is not limited to the following:

    • Droopy eyelid or swelling: More common with prolonged surgeries using a speculum to pry the eye open.
    • Decreased vision or Cystoid macula edema. Found more often with Surgeons using a high level of illumination directly focussed on the eye
    • Retinal detachment : A curtain coming in front of eyes. Highly nearsighted people are more prone to this
    • Dislocated lens material: In cases of complicated surgery
    • Pain : from the increase in intraocular eye pressure
    • Redness : If conunctival tissue has been tampered with by the cataract surgeon
    • Light Sensitivity – multifactorial

Cataract surgery complications, like the ones mentioned above, should be reported immediately to your doctor as soon as you notice them. One reason for this is because in just a few weeks or months post-surgery, the implanted lens can grow in place. This will then become a lot harder for your surgeon to remove or reposition.

Will Smoking Affect My Eye Health?

Whenever you inhale cigarette smoke, nearly 4,000 chemicals are introduced into your bloodstream. If you are a habitual smoker, these chemicals will eventually damage your macula (the center of your retina), resulting in vision problems. Cataracts and macular degeneration are two common consequences of habitual smoking.

Macular degeneration is the leading cause of blindness in people 65+ years old in the United States, and smoking is the number one preventable risk factor of macular degeneration. In fact, according to a 2006 study in the British Journal of Ophthalmology, smoking is directly linked with 25% of macular degeneration cases that end in blindness. Secondhand smoke is also a problem. The study reveals that living with a person who smokes doubles your chances of developing macular degeneration.

Studies also show that the more cigarettes you smoke, and the longer you have been a smoker, the higher your risk of developing cataracts. Heavy smokers are up to three times more likely to have cataracts compared to non-smokers. The free radicals in cigarette smoke increase the oxidative stress in the lens of your eye, damaging important proteins and fiber cell membranes that ultimately result in the opacity of cataracts.

If you are a smoker, or have been a heavy smoker in the past and are concerned about your eye health, please contact The Khanna Institute today or call (877) 254-2662 to schedule an appointment with board-certified Los Angeles ophthalmologist Dr. Rajesh Khanna.

What Causes Cataracts?

Cataracts are cloudy areas that develop in your eye’s natural lens. Although they start out microscopic, cataracts will eventually expand to cover your entire lens, interfering with your vision and potentially leading to blindness. Most cataracts are age-related and begin to form after age 40, though symptoms are not usually noticeable until your 60s.

The clarity of your eye’s lens is maintained by the natural protein fibers within it. As you age, the structure of these protein fibers alters, causing proteins to clump together, which is what results in opacities. These cloudy areas block light from entering your eye and reaching the retina, making your vision appear foggy or dim.

However, not all cataracts are caused by the natural aging process. Sometimes, cataracts can be triggered by:

  • A blunt force injury to the eye
  • Chemical exposure to the eyes
  • Long-term smoking
  • Diabetes
  • Long-term steroid use
  • Hereditary enzyme problems or a metabolic disorder (can cause cataracts in young children)

No matter what has caused your cataracts, Dr. Khanna can help you restore your vision through cataract surgery. This safe and effective procedure has one of the highest success rates in modern medicine. Your cloudy lens will be removed and replaced with an advanced refractive lens, helping you see better than you have in years. Best of all, once your cataracts are removed, there is no chance of them coming back, since cataracts cannot develop on an artificial lens.

If you have further questions about cataracts, please contact The Khanna Institute or call (877) 254-2662 to schedule an appointment with Dr. Khanna. We serve patients throughout Beverly Hills, Westlake Village, and surrounding areas of Los Angeles, California.
