Possible Complications of Cataract Surgery

Possible Complications of Cataract 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.

Differences in Types of Intraocular Lenses (IOLs)

Differences in Types of Intraocular Lenses (IOLs)

Intraocular lens (IOL) implants are used to correct poor vision, whether it is clouded by cataracts or blurred by presbyopia.

With this type of surgery, your eye’s natural lens is replaced by an intraocular lens implant. A monofocal intraocular lens may be implanted to give you a clear point of focus, at a distance or close up.

Types of Multifocal Intraocular Lenses (IOLs)

Because of their ability to correct vision at all distances, multifocal IOLs are the most preferred IOLs. There are three main types:

Multifocal refractive

Multifocal refractive IOLs, like the Tecnis are crafted with several optical zones on the intraocular lens. These different zones allow for various focal points, which improves your vision:

  • At a far distance
  • At intermediate distances
  • At near distances

Apodized diffractive

Apodized diffractive IOLs, like the ReSTOR have gradual diffractive steps on the implant that creates a smooth transition between focal points. This IOL also bends incoming light to the multiple focal points, which enhances vision in different light conditions. Acrysof has recently improved the optical properties of its ReSTOR lenses and released a new version, known as ReSTOR +3.0D. The Khanna Institute is proud to offer this new lens which achieved patient satisfaction rates of 95 % in clinical studies and gave a fourfold increase in the number of patients achieving 20/20 vision or better.

Accommodative

A newer type of IOL, the accommodative, includes lenses such as the Crystalens. These IOLs have one focal point, but act like your natural lens, changing shape to move the single focal point to bring objects at varying distances into focus. Recently, Bausch and Lomb introduced Crystalens HD, which improves depth of focus to improve near vision while maintaining high quality intermediate and distance vision. Khanna Institute of LASIK & Refractive Surgery is proud to offer this new option to our cataract and presbyopia patients.
