Filter by:To evaluate the effect of oral gabapentin premedication on hyperalgesia in elderly patients undergoing staged bilateral cataract operations under monitored anesthesia care
This purpose of this survey study is to collect and describe clinical outcomes for the intraocular lens (IOL) delivery performance of Clareon® IOL AutonoMe™ when used in daily practice.
A study to assess the utility of human polarization pattern perception for the detection, diagnosis and monitoring of eye disease
To determine clinically significant difference in results obtained from cataract surgery using IA. One eye will receive aphakic measurements only and the fellow eye will receive aphakic and then pseudophakic measurements when implanting a toric IOL.
Artificial lenses, otherwise known as intraocular lenses (IOLs), are used to replace the natural crystalline lens within the eye during cataract or refractive lens surgery. Monofocal IOLs are the traditional IOL type used during cataract surgery. These monofocal IOLs provide excellent distance vision, however spectacles are required for reading and intermediate distance tasks. Monofocal Intraocular lenses are the mainstay of cataract surgery, but with advancing technologies and a wider selection of lenses available, demand for improved outcomes, improved lens design and ease of surgical implantation have increased. The purpose of this study is to assess the visual performance of the EyeCee One monofocal intraocular lens. In addition an assessment of the ease of insertion by the surgeon will be quantified.
Pediatric cataract surgery requires the suturing of the corneal incision in order to maintain the integrity of the eyeball and to help avoid the trauma often caused by scratching in the postoperative period of pediatric surgeries. Traditionally, this suturing is performed using 10-0 nylon material. Because this material is non-absorbable, it must be removed under sedation in cases of complications such as suture loosening, late suture lysis, accumulation of secretion on the suture, corneal neovascularization, and corneal ulceration. The objetive of this study is to compare the rate of postoperative complications and the need for suture removal after pediatric cataract surgery in cases in which nylon (non-absorbable) sutures are used versus cases in which polyglactin (absorbable) sutures are used. This is a controlled, randomized, prospective, single-center study performed on patients undergoing pediatric cataract surgery at the Clinical Hospital of the University of Campinas (UNICAMP). The volunteers for whom cataract extraction surgery has been indicated and who have signed the ICF (or whose ICF has been signed by a parent or guardian) will undergo cataract surgery and the cornea will be sutured using a polyglactin 910 suture (Vicryl® 10-0). In the control group (Group B), the cornea will be sutured using nylon 10-0 sutures (the current routine procedure). All patients will be monitored for six months and will receive complete ophthalmological evaluations in order to determine whether they experience any suture-related complications and whether sutures must be removed under sedation. A lower incidence of complications and a less frequent need for suture removal under sedation are expected in the group receiving Vicryl® sutures.
The investigational devices are approved intraocular lenses (IOL) intended to be implanted after phacoemulsification in individuals suffering from age-related cataract with the need of cataract surgery. Within the study, three different IOLs will be investigated and separately evaluated. Cataract surgery with IOL implantation will be performed in subjects who have signed an informed consent form. Postoperative examinations will be postoperative refraction, visual acuity, slitlamp examination, and rotation of the IOL within 1 hour, 1 week, 1 month and 4-7 months. In the Alcon Clareon toric and RayOne EMV toric groups, patients receive a toric IOL according to their preoperative astigmatism
Prospective, non-randomised, open, controlled, single-center post-market clinical follow study about Micropure 1.2.3. and PODEYE intraocular lenses.
To analyze and compare visual results, keratometry, SIA and HOAs outcomes of biaxial microincision cataract surgery in elderly population, including diabetic and non-diabetic patients.
This study is a prospective, multicenter, bilateral, non-randomized, open-label, comparative, 6-month clinical study conducted at up to 50 sites in the USA.
