Active clinical trials for "Cataract"

To demonstrate that the combination formulation of Moxifloxacin/Dexamethasone Eye Drop is effective and safe for the prevention of postoperative inflammation as a consequence of cataract extraction surgery.

The use of one dose of an antibiotic and steroid injected into the eye at the end of cataract surgery is as safe and effective as the post operative use of eyedrops after cataract surgery.

The purpose of this study is to determine the amount of study medication that moves from the front of the eye into the fluid at the front of the inside of the eye.

To compare the efficacy of twice-daily topical bromfenac (Xibrom) ophthalmic solution alone versus twice-daily topical Xibrom with prednisolone acetate 1% three-times daily on visual acuity and OCT measurements.

The purpose of this study is to evaluate the effect that placement and power of the AcrySof Toric has on post-operative visual acuity and spectacle independence for distance vision. This will be determined by comparing manifest refraction pre-operatively and post-operatively and by evaluating the rotational stability of the lens over time.

Visible-light-filtering IOLs are implanted increasingly often in cataract surgery. Several studies examined the effect of light-filters on contrast and colour vision. However, the study outcomes were varying. The present study investigated the effect of two light-filtering IOL on colour perception and contrast acuity using highly sensitive measurement methods.

Purpose: To determine whether implantation of an intraocular lens (IOL) with a modified anterior aspheric surface results in reduced spherical aberration and improved contrast sensitivity after cataract surgery. Design: Prospective, comparative, interventional case series. Methods: In an intraindividual randomized prospective study of 25 patients with bilateral cataract, an IOL with a modified anterior surface (Tecnis Z9001, AMO- Group 1) was compared with biconvex lens with spherical surfaces (ClariFlex®, AMO- Group 2). Ocular aberrations for a 5.0 mm pupil and 6.0 mm pupil were measured with Hartmann-Shack aberrometer. Quality of vision was measured by visual acuity and contrast sensitivity under mesopic and photopic conditions. All patients were followed for 3 months.

The purpose of this study is to evaluate the safety and efficacy of the OptiMedica Femtosecond Laser System to perform surgical maneuvers used in the treatment of subjects with cataracts. The safety and efficacy will be compared to the standard surgical procedure of continuous curvilinear capsulorhexis (CCC) and ultrasonic phacoemulsification.

The purpose of this study was to determine the safety of ranibizumab: a) as a surgical adjunct during cataract surgery in subjects with proliferative diabetic retinopathy (PDR) induced rubeosis and, b) in treatment of proliferative diabetic retinopathy (PDR).

The investigators' purpose is to study the induced refractive change caused by different 2.8-mm corneal incision locations in phacoemulsification, because the investigators hypothesize that the effect may be different for nasal, temporal, and superior location, although they are considered astigmatism neutral. Patients will be randomized to nasal or temporal incision, or assigned to superior incision, depending on preexisting astigmatism. Visual acuity, refraction, keratometry, Pentacam analysis, intraocular pressure, biomicroscopy, and funduscopy, will be carried out before and after phacoemulsification. Outcome measures will be induced corneal refractive change (Fourier power vector analysis), ISV change, and visual acuity, at 6 months.
