Surgical Removal of Idiopathic Epiretinal Membrane With and Without the Assistance of Indocyanine...

Idiopathic Epiretinal MembraneCataract

It was the aim of the present study to prospectively compare the functional and morphological outcome of idiopathic epiretinal membrane surgery with and without the assistance of Indocyanine green (ICG). The main outcome measure was improvement of best-corrected visual acuity (BCVA). This was treated as an open question and we had no hypothesis which of the two therapies was superior.

Absorption of Brimonidine Ophthalmic Solution in the Aqueous Humor of Cataract Patients

Cataract

The purpose of this study is to obtain and assay human aqueous samples following pre-operative dosing with 0.1% Brimonidine Purite™ (pH 7.8) or with 0.15% Brimonidine Purite® (pH 7.2) from patients undergoing routine cataract surgery in order to evaluate the aqueous concentration of the two formulations.Study hypothesis: The aqueous humor concentration 45 minutes following dosing of 0.1% Brimonidine Purite™ (pH 7.8) is comparable with 0.15% Brimonidine Purite® (pH 7.2)

Optimal Method for Mydriasis in Cataract Surgery

Cataract

Obtaining appropriate mydriasis prior to cataract surgery is an important variable in successful surgery. The current practice includes using topical anticholinergic and sympathomimetic agents in the preoperative area prior to cataract surgery, but the pupils are sometimes insufficiently dilated and can often need additional mydriasis with intracameral agents during cataract surgery. Pre-operative topical mydriatic drops take time to take effect, are mildly uncomfortable for the patient, and have a cost to the healthcare system. If intracameral mydriasis alone can achieve adequate pupil dilation, perhaps topical mydriatics would not be needed. The purpose of this study is to evaluate whether topical versus intracameral versus topical + intracameral mydriasis is the optimal way to dilate pupils during routine cataract surgery. The results of this study have implications for improving the efficiency and reducing time prior to cataract surgery. In addition, it has significant potential to reduce the cost associated with cataract surgery if preoperative drops can be eliminated.

Comparison of Epinephrine and Phenylephrine/Ketorolac With Regards to Pupil Size

Cataract

The objective of this study is to compare the maintenance of intraoperative mydriasis during cataract surgery between two drugs: epinephrine, which has routinely been used for decades, and Omidria, a newly FDA approved combination drug of phenylephrine and ketorolac. Patients undergoing cataract surgery that are enrolled in the trial will randomly receive one of the drugs in one eye, and the other eye will receive the drug during the subsequent cataract surgery.

Effect of Chitosan-N-Acetylcysteine on IOL-power Prior to Cataract Surgery

Eye Diseases

Aim of this study is to evaluate the effect of treatment with Lacrimera® on calculated IOL power prior to cataract surgery and on the stability of ocular surface parameters compared to preservative-free, Hyaluronic-acid containing eyedrops (Hylo-Vision® sine).

Study of OT-551 Eye Drops to Prevent or Delay Progression of Nuclear Cataracts Following Vitreous...

Epiretinal MembraneMacular Hole

The purpose of this trial is to compare the ability of two doses of OT-551 ophthalmic solution and drug-free solution to safely and effectively prevent or delay the progression of nuclear cataracts that frequently develop as a result of vitrectomy (surgery for retina repair), thereby avoiding the need for a second surgery (cataract removal). Victrectomies involve removal of the jelly-like substance (vitreous) that is located in a cavity behind the lens.

Effect of Preoperative Topical Ketorolac on Aqueous Cytokine Levels and Macular Thickness in Cataract...

Cystoid Macular EdemaPostoperative1 more

The purpose of this study is to determine whether there is a relationship between inflammatory cytokines in the aqueous of the eye and thickness of the macula after treatment of topical ketorolac for patients undergoing cataract surgery.

Evaluation of Meibomian Gland Dysfunction Before and After Cataract Surgery

Cataract Patients

This study will compare cataract patients before and after phacoemulsification. Evaluations will be performed before and 1 and 3 months following cataract surgery, including parameters of dry eye syndrome and MGD. Dry eye syndrome parameters included TBUT, Schirmer's test type I, Oxford staining score, and the Ocular Surface Disease Index (OSDI) Questionnaire. MGD parameters consisted of lipid layer thickness (LLT), lid margin abnormality, meibum quality, meibum expressibility, MG orifice obstruction, MGD stage, and MG dropout.

Intravitreal Dexamethasone Implant (Ozurdex) Versus Bevacizumab in Patients With Diabetic Macular...

Diabetic Macular EdemaCataract

The purpose of this research is to compare the effectiveness of bevacizumab (Avastin) with another a dexamethasone implant (Ozurdex), with respect to anatomic and visual outcomes as well as injection frequency in subjects undergoing cataract surgery with a concurrent diagnosis of diabetic macular edema (DME).
