Clear lens extraction
Clear Lens Extraction
Clear lens extraction (pronounced: kleer lenz ek-strak-shun), also known as Refractive Lens Exchange (RLE) or Lens Replacement Surgery, is a surgical procedure that involves the removal of the eye's natural lens which is clear and replacing it with an artificial lens. This procedure is typically performed to correct refractive errors in the eye.
Etymology
The term "clear lens extraction" is derived from the English words "clear" (meaning transparent), "lens" (referring to the lens of the eye), and "extraction" (meaning to remove). The term accurately describes the procedure as it involves the removal of the clear, natural lens of the eye.
Procedure
The clear lens extraction procedure is similar to cataract surgery. The surgeon makes a small incision in the cornea, the clear front part of the eye. A small instrument is then used to break up and remove the clear lens. Once the natural lens has been removed, it is replaced with an artificial lens, known as an intraocular lens (IOL). The IOL is selected to match the patient's refractive error, allowing for improved vision post-surgery.

- Phacoemulsification: A modern cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye.
Risks and Complications
As with any surgical procedure, clear lens extraction carries potential risks and complications. These may include infection, inflammation, increased eye pressure, retinal detachment, and changes in vision. It is important for patients to discuss these risks with their ophthalmologist before deciding on the procedure.
