Filter by:Clonidine, an agonist for alfa2 pre-synaptic, has been shown to be an effective adjuvant therapy for acute postoperative pain and has been shown an effect in sedative, intra-ocular and blood pressure and arrhythmias.The objective of this study is evaluating the analgesic effect of clonidine and its repercussion on arterial and intraocular pressure and arrhythmias for cataract surgery.
To evaluate the safety and efficacy of OTX-DP as a sustained release drug (dexamethasone) depot when placed in the canaliculus of the eyelid for the treatment of ocular inflammation and pain in subjects who have undergone cataract extraction with intra-ocular lens implantation.
Aravind Eye Hospital and the University of California, San Francisco (UCSF) Proctor Foundation collaborated on the Antioxidants for the Prevention of Cataract Study from 1997-2002. (1) In the study, 798 participants aged 35-50 years were enrolled from 5 rural villages, and randomized to thrice weekly antioxidants (vitamin C, 500 mg; beta carotene, 15 mg; and alpha-tocopherol, 400 IU) or placebo. After 5 years of supplementation, there was no significant difference in cataract formation between the antioxidant group and placebo. In this follow-up study, we will return to study villages to determine whether rates of cataract surgery are different in the 2 groups. 1. Gritz DC, Srinivasan M, Smith SD, et al.

With age, a human crystalline lens opacifies (cataract) disabling the eye in generating a clear, well contrasted image. The only therapeutic solution to this problem is surgical replacement of the crystalline lens with an intraocular lens (cataract surgery). In addition to the cataract, the person might suffer from pre-existing cormeal astigmatism. In cases of severe corneal astigmatism, the standard IOL might not provide the optimal result, and additional surgical procedures as Incisional Keratotomy or Limbal Relaxing Incisions might be required. BunnyLens TR IOL is an Aspheric Toric intraocular lens providing a precise, superior alternative to surgical treatment of pre-existing corneal astigmatism. The BunnyLens TR IOL is designed for micro-incision cataract surgery (MICS), through 1.8mm incisions. The aims of this study are to: - Demonstrate a reduction in refractive cylinder compared to pre-operative corneal astigmatism - Exceed monocular best corrected distance visual acuity results provided in ISO guidelines.
The purpose of this study is to evaluate efficacy and safety of the ophthalmic solution PRO-155 in patients post phacoemulsification.
The main objective of this research is to assess visual function and optical performance of CE marked, implanted intraocular lenses to understand the individual factors that affect their performance and how these may be improved in future designs and to evaluate measurement techniques. All outcome measures will be captured 3-6 months after surgery
Effectiveness of lutein, zeaxanthin and trypan blue to stain the anterior lens capsule during cataract phacoemulsification.
The objective of this study is to evaluate clinical outcomes following sub-2 mm micro-incision cataract surgery (MICS) and intraocular lens (IOL) implantation. This study is evaluated in two Phases - V4 (6M) endpoint: primary analysis - V5 (12M) and V6 (34M): EPCO score and Nd Yag incidence analysis
This is a safety and efficacy study of a Dexamethasone Drug Delivery System for anterior segment inflammation and pain following cataract extraction with lens implantation.
The purpose of this study is to evaluate the visual performance of a trifocal intraocular lens at distance, near and intermediate viewing, by way of visual acuity measurement, contrast sensitivity. Patient satisfaction and quality of vision will also be assessed by way of a questionnaire.
