The use of a flexible IOL enables the lens to be rolled for insertion into the capsular bag through a very small incision, thus avoiding the need for stitches. This procedure usually takes less than 30 minutes in the hands of an experienced ophthalmologist, and the recovery period is about 2–3 weeks. After surgery, patients should avoid strenuous exercise or anything else that significantly increases blood pressure. They should visit their ophthalmologists regularly for 3 weeks to monitor the implants. IOL implantation carries several risks associated with eye surgeries, such as infection, loosening of the lens, lens rotation, inflammation and nighttime halos, but a systematic review of studies has determined that the procedure is safer than conventional laser eye treatment. Though IOLs enable many patients to have reduced dependence on glasses, most patients still rely on glasses for certain activities, such as reading. These reading glasses may be avoided if Multifocal IOLs, Trifocal IOLs or EDOF lenses are used. Medical uses
Intraocular lenses have been used since 1999 for correcting larger errors in near-sighted, far-sighted, and astigmatic eyes. This type of IOL is also called phakic intraocular lens (PIOL), as it is implanted without removing the patients natural crystalline lens.Phakic IOL appear to be less dangerous than excimer laser surgery (LASIK) in those with significant nearsightedness.More commonly IOLs are implanted via Clear Lens Extraction And Replacement (CLEAR) surgery.
