Ophthalmologists perform lens implantation surgery after cataract surgery so patients can enjoy clear vision without the need for thick glasses or special contact lenses, states EyeSmart. The lens implant is made of flexible material, and the doctor puts in the prescription that leaves the patient with the best possible vision.
The doctor removes the original lens of the eye during a cataract surgery, according to EyeSmart. After the surgery, the implant works the same way as the original lens. Doctors often prefer to perform this surgery after removing a cataract from one eye because wearing a pair of glasses with one medicated lens decreases binocularity, states the American Association for Pediatric Ophthalmology and Strabismus.
