2. Cataract surgery - Wikipedia

   en.wikipedia.org/wiki/Cataract_surgery

   Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [1] The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.

3. Intraocular lens - Wikipedia

   en.wikipedia.org/wiki/Intraocular_lens

   During CLEAR, the crystalline lens is extracted and an IOL replaces it in a process that is very similar to cataract surgery: both involve lens replacement, local anesthesia, last approximately 30 minutes, and require making a small incision in the eye for lens insertion. People recover from CLEAR surgery 1–7 days after the operation.

4. Phakic intraocular lens - Wikipedia

   en.wikipedia.org/wiki/Phakic_intraocular_lens

   A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.

   Cataracts cause the lens of the eye to become cloudy over time, but if they are left untreated, they can lead to complete blindness. While cataracts are unable to spread from one eye to another ...

6. History of cataract surgery - Wikipedia

   en.wikipedia.org/wiki/History_of_cataract_surgery

   Cataract surgery is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [3] Over time, metabolic changes of the crystalline lens fibres lead to the development of a cataract, causing impairment or loss of vision.

7. Phacoemulsification - Wikipedia

   en.wikipedia.org/wiki/Phacoemulsification

   Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure.
