CATARACTS BY TYPE

There are three primary types of age-related cataracts. A “nuclear sclerotic” cataract is characterized by clouding and hardening of the eye lens at its center. When a nuclear cataract first develops, it can bring about a brief improvement in near vision (“second sight”), which is only temporary. A “cortical” cataract forms on the periphery of the lens cortex and develops spoke-like projections that extend from the outside of the lens toward the center. A “posterior subcapsular” cataract begins at the back of the lens. This type of cataract may develop in those with diabetes or patients […]

While “laser-assisted in situ keratomileusis” (LASIK) surgery may be a very good way for younger patients, in particular, to correct refractive errors (nearsightedness, farsightedness, and astigmatism), “lens replacement surgery” (LRS) may be a better option for older patients. Unlike LASIK, which involves reshaping the cornea (the clear front surface of the eye), LRS encompasses replacing the eye lens with an implant. Doing so with a high-tech, multifocal intraocular lens (IOL) helps older patients overcome the effects of “presbyopia” (age-related lens inflexibility that necessitates reading glasses) and cataracts. LRS works best […]
