Intraocular lenses, or IOLs, are implantable lenses that are used to replace the natural lenses of the eyes when they have become damaged.Scientists originally designed IOLs to treat cataracts.I did consider having Lasik, but the combination of high Myopia and thin Cornea meant I was a borderline case.In contrast, my wife Wendy at -3 diopters had Lasik done in 2002 by Dr. Keller of Boulder Eye Surgeons (ironically our neighbor across the street) and she had excellent results.Around age 40, it slowly started becoming more difficult to focus (when wearing correction) at close distances, especially in low light.This is a very common condition called Presbyopia which is due to your crystalline lens becoming less elastic.I had Symfony lenses implanted in both eyes the first week of December.By 1 week postop my uncorrected vision at distance was between 20/15 and 20/20.
In some cases, IOLs can also correct myopia, or nearsightedness. Choices include monofocal, multifocal, and toric lenses.The lens and ciliary muscle are connected by a 360-degree series of fibers (called ciliary zonules) that extend from the ciliary muscle to the thin lens capsule (or "bag") that encloses the lens.The ciliary muscle, ciliary zonules and lens capsule keep the lens suspended in its proper position inside the eye for clear vision.As scientists continue to research cataracts and ocular health, we are likely to see even more types of IOLs.Nevertheless, today's lenses offer outstanding results. Most patients are happy with their procedures, and they enjoy significantly improved vision.
At near my vision was already about 20/25 (but fluctuating a bit it had seemed better earlier that day).
