Iris Claw lens Surgery in Ambala
What are Secondary IOLs?
A lens implant is a small, plastic lens that an eye provider can put in your eye to replace a lens that has been removed because of a cataract. Usually the plastic lens is implanted during surgery to remove the cataract. A secondary lens implant is one that is done in a separate surgery after cataract surgery. A number of techniques and IOLs are available for secondary IOL implantation
Iris Claw Lens
Secondary iris claw intraocular lens implantation is a viable option to correct monocular aphakia in eyes without capsular support. Aphakia comes from two Greek words: “a” meaning “none” and “phacos” meaning “lens.” In aphakia, there is no crystalline lens inside the eye.
Iris-Claw IOL is a safe procedure and an effective option for aphakic eyes with no capsular or zonular support. Posterior chamber iris-claw lenses are a good option in eyes with inadequate posterior capsular support. Chronic inflammation, poor lens stability, or significant central endothelial cell loss was not observed during the 6-month follow-up period.
Scleral Fixated Intraocular Lens
Intraocular lenses (IOLs) can have inadequate support for placement in the capsular bag as a result of ocular trauma, metabolic or inherited conditions such as Marfan’s syndrome or pseudoexfoliation, or complicated cataract surgery. Surgical options for patients with inadequate capsular support include alternative placement in the anterior chamber (ACIOLs), fixation to the iris, or fixation to the sclera. The surgical techniques for each of these approaches have improved considerably over the last several decades resulting in improved visual and ocular outcomes. If no capsular or iris support exists, the surgeon can fixate an IOL to the sclera or the patient can remain aphakic. IOLs can be fixated to the sclera using sutures or by tunneling the IOL haptics into the sclera without sutures. This review summarizes the pre-operative considerations, surgical techniques, outcomes, and unique complications associated with implantation of scleral-fixated IOLs.
Aniridia Lens
The Aniridia Lens offers solutions for the correction of aniridia as well as iris coloboma.
