Astigmatism – Everything you wanted to know about it

Scleral Contact Lenses – a new hope

SCLERAL LENSES

If you have actually been told in the past that you cannot wear contact lenses due to an irregular cornea or various other problems, you might wish to get a second opinion and also ask your ophthalmologist regarding scleral contact lenses.

Scleral contacts are large-diameter or larger in size than normal contact lenses or gas permeable contact lenses specially designed to vault over or cover the whole corneal surface area and also hinge on the "white" of the eye (sclera). In doing so, scleral lenses functionally replace the irregular cornea with a flawlessly or perfectly smooth optical surface area to correct vision problems caused by keratoconus and various other corneal irregularities.

Additionally, the space in between the cornea and the back surface area of a scleral lens acts as a fluid reservoir to provide convenience for individuals with extreme dry eyes that otherwise might not endure contact lens wear.

Types of Scleral Lenses

Scleral contacts are significantly bigger than conventional gas permeable General Practitioner contacts and have a diameter equivalent to or greater than that of soft contact lenses. The smallest sclerals are around 14.5 mm in diameter, and also the biggest can be approximately 24 mm.

How a scleral lens vaults over a misshapen cornea to assist somebody with keratoconus see far better.

Large-diameter scleral and semi-scleral General Practitioner lenses hinge on the sclera and vault over the irregular cornea of an individual with keratoconus, for better vision. Increase the size of generally lenses that are 18 mm or smaller are subcategorized as mini-sclerals.

The ordinary human cornea is around 11.8 millimeters in diameter, so also the smallest scleral contacts are developed to cover the entire} corneal surface area.

In contrast, the majority of traditiona General Practitioner contact lenses are 9.0 to 9.5 mm in size and cover only 75 to 80 percent of the cornea.

An additional category of gas permeable lenses bridges the size gap between traditional General Practitioner lenses and mini-sclerals. These lenses, called corneo-scleral lenses, normally are roughly 13 to 15 mm in diameter.

Corneo-scleral lenses often} are a great {option for people who require larger-than-normal General Practitioner lenses for betterconvenience}. They also are frequently used when contact lenses are required after LASIK or other corneal refractive surgical treatment to correct irregular astigmatism.

The dimension of lens used usually is identified by the level of complexity of the condition. Milder types of keratoconus and irregular astigmatism from corneal grafts as well as refractive surgical treatment frequently are conveniently managed with scleral lenses at the smaller sized end of the spectrum.

Smaller sized scleral and mini-scleral contacts can be much easier to apply, can be less expensive and need less} care products

Much more complicated problems, consisting of advanced keratoconus, pathologically dry eyes or serious eye surface condition that may call for a huge tear storage tank, commonly are fitted with bigger scleral lenses, as they have a lot more capability to hold liquid or bridge huge adjustments in corneal curvature.

Throughout your contact lens examination as well as fitting, your eye treatment expert will certainly establish the most effective scleral lens type and also size for your particular requirements.

Scleral Contact Lenses for Keratoconus

In instances of very early keratoconus, a common GP lens might be made use of.  Nevertheless, if the lens does not center correctly on the eye or moves excessively with blinks and also triggers discomfort, switching over to a large-diameter scleral contact lens might solve the problem.

Since scleral lenses are developed to rise the corneal surface and also hinge on the much less sensitive surface area of the sclera, these lenses usually are much more comfy for an individual with keratoconus.

Additionally, scleral lenses are developed to fit with little or no lens activity or movement during blinks as they are hinged on the sclera, making them much more stable on the eye, compared to conventional corneal gas permeable lenses.

Scleral Contact Lenses for Various Other Eye Troubles

Along with keratoconus, scleral contact lenses can be utilized for various other eye problems such as eyes that have actually undergone a corneal transplant, and also for individuals with serious completely dry eyes triggered by problems such as Sjogren's disorder, graft-versus-host disease (GVHD) and also Stevens-Johnson disorder.

Advancements in lens design technology are enabling makers to develop scleral lenses that can remedy a lot more problems than ever, consisting of bifocal sclerals for the correction of presbyopia.

Special-Effect Scleral Contacts

Often the term "scleral lenses" (or "sclera lenses") additionally is used to explain special-effect contact lenses that significantly change the look of the user's eyes.

Nevertheless, these costume contact lenses also called theatrical contact lenses, Halloween contacts or gothic lenses generally are soft lenses that bear little resemblance to scleral gas permeable contacts in -- apart from their big diameter size to completely mask the cornea. Likewise, soft theatrical contacts generally are made for aesthetic functions just and not for vision correction.

Scleral contact lenses are tailor-made for every user, so suitable scleral contacts needs better know-how as well as even more time than fitting conventional soft or GP contact lenses.

How to fix lazy Eye

How to Fix a Lazy Eye

How to Fix a Lazy Eye is a question often posed by young parents. Lazy Eye is a term used to define an eye that cannot see to its full potential. You may be aware normally an eye should see 20/20. That means that a person standing at 20 feet should see what a normal person sees at 20 feet. If a normal person can see at 40 feet what you see at 20 feet than your vision is 20/40. If after correction with glasses or contact lenses the vision does not improve to 20/20 than the eye is termed as Lazy. The medical nomenclature is Amblyopia.

Let us understand why an eye becomes lazy. The role of eye is transfer information from the surrounding universe to the brain. The eye condenses the light reflected from various objects on the macula. Electric signals generated are transferred to the brain by optic nerve. A specialized area of the brain called the occipital lobe converts these neuroelectrical signals into vision.

Any flaw in this process leads to an Amblyopic or Lazy Eye. There are three types of Lazy Eye.

The first kind is Neurological. This occurs when there is an obstruction in the neurological pathway or the brain. If the optic nerve is not developed, or the conduction pathways are malformed the light is not transmitted to the grey matter. Also the brain may be underdeveloped due to infections or genetic causes. This is the most challenging kind; currently this is not amenable to treatment.

The second kind is deprivation amblyopia. If the light is prevented from reaching the macula, it fails to stimulate the brain. There are various causes for this. Cornea may be opaque. There may be cataract in the lens. The jelly behind the lens may be fibrotic and hazy. The good news is that treatment can be provided. The earlier it is instituted the better the chance of fixing the lazy eye. Cataract procedure may have to be performed even before the baby is one year of age.

The third kind is refractive Amblyopia. The cause is nearsightedness, farsightedness or astigmatism. When the eye is very small or very large or has astigmatism significantly higher than the corresponding eye it is at risk of developing Amblyopia. Here the light reaches the macula and messages are delivered to the brain. But the messages are distorted. Since the brain keeps receiving information it has the best potential to recover.

How to Fix a Lazy Eye caused by Refractive Error

The way to do this is to fix the refractory error. The correct procedure would be influenced by the age and the refractive power. If the numbers are in the range of Lasik eye surgery this may be the simplest procedure. In such instances Lasik may even be performed on kids as young as six years. Sometimes an artificial lens may need to be implanted over the natural lens. If the person is above fifty years of age a presbyopic implant may be the best option.

In summary Refractive Amblyopia has the best chance of improving. This is possible in kids, young adults and even older individuals.

How to fix Astigmatism

Is Your Astigmatism Bothering you?

Do you or someone you know suffer from headaches, eyestrain, squinting, and distorted or blurred vision? If so, you may suffer from astigmatism, but do not fret! Astigmatism is not a disease it is merely a refractive error, caused by an irregularly shaped cornea which hinders how your eye absorbs light. Lucky for you, in this day and age there are many ways on how to fix astigmatism! You will find three of these ways listed below.

How to fix Astigmatism in the 21st century

One way to fix astigmatism is through a procedure called Customvue Wavefront Laser Vision Correction, or Lasik eye surgery. Through Lasik eye surgery, we are able to reshape the cornea, which in turn decreases or completely eliminates the refractive error of the eye, aka the astigmatism.

Another way is through Limbal Relaxing Incisions, or LRI. In LRI, small incisions are made at opposite ends of the cornea. Once the incisions heal the cornea becomes more spherical in shape and helps to reduce or eliminate astigmatism.

The last way we are going to cover is through the use of Toric Implantable Lenses.  These are premium intraocular lenses that correct not only astigmatism, but also near and farsightedness.  These lenses are able to correct astigmatism, because they have different powers in different meridians of the lens. The surgeon is able to adjust the orientation of the lens inside the eye by using the alignment markings on the peripheral lens, optimizing astigmatism correction.

How to fix astigmatism

If you believe you may be suffering from astigmatism, help is here. There is no need to suffer any longer! Through Customvue Wavefront Laser Vision Correction, Limbal Relaxing Incisions, and Toric Implantable Lens, there are plenty of ways to fix astigmatism.

A consultation with an expert in astigmatism correction will be beneficial to you. Feel free to contact us and we may even be able to offer you a free screening visit. Call Now 310 482 1240
