Accommodative intraocular lenses for age-related cataracts.
The standard intraocular lens (IOL) that is used to replace a cataractous lens cannot change focus from distant to near objects, so most patients need glasses for near vision after cataract surgery. Limited evidence suggests that accommodative IOLs provide better near vision than monofocal IOLs, but not better than multifocal IOLs. Long-term follow-up is needed to confirm patient outcomes, and ...
متن کاملBiocompatibility of Intraocular Lenses
The performance of an intraocular lens is determined by several factors such as the surgical technique, surgical complications, intraocular lens biomaterial and design, and host reaction to the lens. The factor indicating the biocompatibility of an intraocular lens is the behavior of inflammatory and lens epithelial cells. Hence, the biocompatibility of intraocular lens materials is assessed in...
متن کاملPhakic intraocular lenses.
The main objective of refractive surgery is improving the patient’s quality of life by decreasing their dependence on spectacles and contact lenses. In the majority of cases, we, refractive surgeons, are dealing with young healthy individuals with excellent quality of vision; they are seeking no less than excellent uncorrected visual acuity with at least the same quality of vision postoperative...
متن کاملAspheric Intraocular Lenses
With continued improvements in surgical techniques, biometry, and intraocular lens (IOL) technology, cataract surgeons have for some time been capable of consistently achieving highly accurate quantitative refractive results following cataract/lens replacement surgery. We know we can improve an individual’s vision from 20/400 to 20/20, for example. The modern cataract surgeon, however, is now e...
متن کاملScleral Fixation Intraocular lenses
Background: The 1ry indication for scleral fixation of intraocular lenses (IOL) is dislocation as a principal complication of cataract surgery. Inadequate capsular support is the most common cause of IOL dislocation. Other indications include traumatic phakic lens dislocation (cataractous or clear), surgically aphakic eyes or anterior chamber IOL with complications (persistent hyphema, uveitis)...
