Refractive Intraocular Lens Implantation
An intraocular lens is a plastic transparent lens, made in various shapes and different optical powers in order to meet all patients' needs. There are concave lenses (-) convex lenses (+) and cylindrical lenses to correct astigmatism.
Intraocular lens Insertion
The attending opthmologist relies on tests results and clinical examinations of the eye to select the best IOL type implant for each patient. There are two methods for intraocular lens implant depending on its type:
· Intraocular lens is implanted inside the anterior chamber of the eye (between cornea and iris). Ophthalmologist usually use this method for patients who suffer from severe myopia/hyperopia without astigmatism.
· Intraocular lens is implanted in the posterior chamber of the eye
(Between the iris and the crystalline lens). Ophthalmologist usually use this method for patients who suffer from severe myopia/hyperopia and astigmatism.
In both cases, eye measurements are taken into consideration in selecting lens size.
Who can Undergo IOL Implant?
· Patients over 21 years of age; where both optical power and eye parameters have stabilized.
· Patients whose tests results and clinical examination indicate that the eye is suitable for IOL implant.
· Patients with moderate to severe myopia or hyperopia with or without astigmatism.
