As we age, our eyes undergo changes, one of which is the development of cataracts. A cataract occurs when the lens of the eye becomes cloudy, hindering the passage of light and resulting in blurry vision and other associated symptoms. Thankfully, cataract surgery offers a solution to this common problem.
During cataract surgery, the cloudy lens is surgically removed and replaced with a clear artificial lens. This procedure aims to restore your vision and alleviate the symptoms caused by cataracts.
Who is a Candidate for Cataract Surgery?
Various factors can contribute to the development of cataracts, including natural age-related changes. Additionally, habits such as smoking, excessive alcohol consumption, and prolonged exposure to sunlight can expedite the formation of cataracts. Certain health treatments and conditions such as diabetes, long-term steroid use, radiation exposure, and previous eye surgeries for other vision issues can also increase the risk of cataracts.
If a person’s vision is affected by cataracts or if their doctor needs to examine the back of their eye to address other vision problems, cataract surgery becomes necessary.
Intraocular Lens Types
When it comes to cataract surgery, the doctor replaces the cloudy lens with an artificial intraocular lens. These lenses come in various types, some of which can even eliminate the need for glasses altogether.
One of the most common types is the monofocal intraocular lens. These lenses are designed for either close, medium, or long-range vision. Typically, individuals opt for a monofocal lens to improve long-distance vision and continue to use reading glasses as necessary.
Alternatively, multifocal intraocular lenses are available, which provide simultaneous near and far focus. Accommodative intraocular lenses are another option, enabling individuals to focus at different distances. Lastly, there are toric intraocular lenses that correct refractive errors for individuals with astigmatism.
