Cataract surgery is different from lasik ( surgery done to correct power of eyes ) .during cataract surgery ,your ophthalmologist remove the cataract lens and replace it with artificial IOL Where else in lasik the black part of the eyes ( cornea) is corrected to achieve clear vision without glasses. – Presbyopia is a condition most people over the age of 40 experience that results in difficulty seeing up close without the aid of bifocals, trifocals, or reading glasses. – This age-related condition is believed to be caused by a hardening of the lens inside the eye, making it difficult for the eye muscles to focus. – This can be corrected during Custom Cataract Surgery using a multifocal or presbyopia-correcting IOL. – Another type of premium lens available is a Toric (monofocal) IOL that can correct astigmatism. – Astigmatism is caused by the cornea being shaped more like a football than a basketball, which results in images focusing at different points in the retina. As everyone’s eyes vary, you will need to meet with your ophthalmologist to determine if one of these premium lenses can help reduce or eliminate your dependency on glasses after your cataract surgery.
