A clouding develops in the crystalline lens of eye or in its envelope. This varies in degree from slight to complete opacity and obstructing the passage of light. This development of clouding is called Cataract. Some of the symptoms and how they progress are given here.
Early in the development of age-related cataract, the power of the lens may be increased, causing
near-sightedness (myopia), and the gradual yellowing and opacification of the lens may reduce the perception of blue colours.
Cataracts typically progress slowly to cause vision loss, and are potentially blinding if untreated. The condition usually affects both eyes, but almost always one eye is affected earlier than the other.
In the elderly, a senile cataract is characterized by an initial opacity in the lens. Subsequent swelling of the lens and final shrinkage with complete loss of transparency.
Untreated, the cataract can cause phacomorphic glaucoma.
Cataract Operating Procedures
In this Rigid IOL will be implanted through 5 mm incision
Referred as modern cataract surgery Phacoemulsification is also commonly called as Laser Cataract Operation.
TYPES OF IOL
There are so many types of Intraocular lens that have been available with the advancement of technology. Commonly used IOLs are listed below.
Rigid IOL - These IOL can be implanted in Manual SICS through 5 mm incision.
Foldable IOL(2.8 mm to 1.8 mm)
Monofocal IOL: Monofocals will correct the distance vision only and will be a good choice for patients who wants to wear reading glasses after surgery.
Multifocal IOL: Multifocal IOL will correct both distance and near vision and are best for patients who desire both good distance and good reading
vision without glasses.
Toric IOL(mono focal/multifocal): Toric IOLS are best for patients with significant Astigmatism who desire less dependency on glasses to give clear
Accommodative IOL: In these IOLs use materials and techniques that allow the IOL to flex via contraction of the ciliary body , thus shifting the focal
point from distance to intermediate and from intermediate to near. These IOL are best for patients who are able to achieve good uncorrected distance and intermediate vision.
Scleral fixated IOL(suture/glued IOL): These IOL are safe and effective in Optical Aphakia, Zonular dialysis weak capsular support ,Traumatic cataract
with Posterior capsular dehiscence.
