Filter by:The purpose of this study is to evaluate the safety and performance of the SBL-3 intraocular lens.
This randomized clinical trial compares subjective performance during Intraocular lens (IOL) implantation, as well as incision enlargement and anterior segment morphology on OCT when IOL implantation was performed during microcoaxial phacoemulsification through a 2.2mm incision using one of three injectors : Manual screw type (Monarch III), Manual plunger type (Royale) and motorised injector (Autosert). Further, the investigators also looked at incision integrity by comparing ingress of trypan blue from the ocular surface into the anterior chamber.
In this study, the investigators introduce a new "capsule-reserved" cataract surgical procedure in which anterior lens capsule is reserved and attached onto posterior lens capsule in the purpose of preventing posterior capsule opacification (PCO). A prospective randomized controlled study is reported to compare the new "capsule-reserved" surgical procedure with conventional one on the effectiveness to prevent posterior capsule opacification in age-related cataract patients.
During cataract surgery, it is necessary to dilate the iris in order to remove the crystalline lens and position the implant. The diameter of the optical implant being 6 mm, in case of capsulorhexis crystalline access 5.5 mm, the expansion should be at least 6 mm. At pre-operative consultation, the iris is always dilated by instillation of eye drops and measured at the slitlamp. For patients with an inadequate dilation, the intervention requires the use of a mechanical dilatation device. This study aims to assess the value of an alternative dilatation ring to Malyugin ring, which can be inserted and removed through an incision of less than 2 mm in diameter, due to its size smaller than that of the Malyugin ring. Our hypothesis is that this Bhattacharjee ring ensures sufficient and stable iris dilation during surgery, enabling implant placement in good conditions.
The aim of this study is to evaluate the efficacy of selective laser trabeculoplasty after a prior failed phacoemulsification and Eximer Laser Trabeculectomy.
The study is an observational non-randomised controlled study comparing the visual acuity after implantation of the POD 26% FINEVISION TORIC with respect to the POD 26% TORIC
This study will compare cataract patients with implantation of diffractive multifocal IOL with an additional power of +2.75 diopters (Group 1) and with +3.25 diopters (Group 2). Evaluations will be performed 1 and 3 months following cataract surgery, including measurement of uncorrected distance visual acuity (UDVA), refractive error (manifest refraction [MR]), and uncorrected near visual acuity (UNVA) at 33, 40, and 50 cm. At 3 months, internal aberrations and contrast sensitivity will be evaluated and subjects will complete a questionnaire on outcomes satisfaction, visual symptoms, and spectacle use.
To study the effective lens position concept in second eye refinement (SER) cataract surgery, by relating inter-ocular symmetry of pseudophakic anterior chamber depth (pACD) measured in Pentacam and SER refractive outcomes.
To investigate the possible mechanisms by which cataract surgery aggravates meibomian gland dysfunction (MGD), the investigators evaluated the changes in tear cytokines and ocular surface parameters after cataract surgery according to the preoperative MGD grade.
The purpose of this clinical trial is to evaluate the effectiveness of the PRECIZON Presbyopic.
