Glaucoma is a common eye condition in which the fluid pressure inside the eye rises to a level higher than healthy for that eye. If untreated, it may damage the optic nerve, causing the loss of vision or even blindness. The treatment of glaucoma may include medication, surgery, or laser surgery. Eyedrops or pills alone can usually control glaucoma, although they cannot cure it.
Hydrus™ Is a Microstent, developed by Ivantis, for the treatment of patients with primary open angle glaucoma (POAG). The Hydrus procedure is designed to be less invasive than traditional glaucoma surgery and can be performed during cataract surgery using the same microsurgical incisions. The enrollment for this study is closed.
The Raindrop® (Revision Optics) Near Vision Inlay is a microscopic transparent hydrogel inlay that is designed to correct presbyopia. Raindrop® is the first and only corneal inlay that creates a prolate-shaped cornea, and is easily placed under a femtosecond laser flap. This study is being conducted in patients who underwent cataract surgery in the past, and want improvement of near visual acuity.
Another alternative to correct presbyopia is the VisAbility scleral Implant System (Refocus).The procedure is a minimally invasive outpatient procedure, which typically takes 20 to 30 minutes per eye. Four small plastic implant segments (about the size of a grain of rice) are surgically placed into the white of your eyes. The segments are small, normally hidden by the eyelids and are generally not noticeable after placement. It is anticipated that these implant segments will create additional space inside the eye to restore the natural tension of the muscle tissue inside the eye.
Astigmatism is a condition where the cornea (front surface) of the eye, is not curved uniformly, it is shaped more like a football than spherical like a baseball. With astigmatism, the light rays passing through the cornea do not focus on a single point of the retina. This may cause objects both near and far away to appear blurry, shaded or elongated. An intraocular lens designed to reduce astigmatism is called a “toric” IOL. Cataract patients who have astigmatism, and who do not want to wear glasses to see clearly at distance can choose Toric intraocular lenses to be implanted during surgery.
We are conducting two different studies related with Toric intraocular lenses.
4. POST-APPROVAL STUDY OF THE TECNIS TORIC IOL MODELS ZCT300 AND ZCT400.
This study sponsored by Abbott evaluates the rates of visual distortion in patients with cataract implanted with the TECNIS Toric IOLs (ZCT300 and ZCT400) The TECNIS Toric IOLs are marketed in the US, Europe and other countries worldwide.
5. Clinical performance of the Cassini TCA for Toric IOLs
This study enrolls patients that will have cataract surgery with Toric intraocular lenses, used to correct astigmatism, and compares actual and simulated Toric IOL calculations with different keratometric measurement devices, including the Cassini topographer.
