Filter by:The goal of this clinical trial is to learn if an app-based vision testing (WHOeyes) combined with a questionnaire can recognize those who have to go back to the hospital, and thus replace the in-clinic 1-week review after an uncomplicated cataract surgery in people with senile cataract. It will also learn about the cost-effectiveness and environmental benefits of such remote follow-up pattern. Besides, the safety and user's satisfaction will also be evaluated. The main questions it aims to answer are: For people with uncomplicated senile cataract, does 1-week clinical follow-up replaced with remote follow-up (using a vision test app and a questionnaire) not adversely affect patients' prognosis? Can this alternative approach bring greater cost-effectiveness and environmental friendliness compared to the traditional follow-up method? Researchers will compare one-week remote follow-up to a routine clinical follow-up to see if one-week remote follow-up is feasible. Participants will: Visit the clinic to finish routine follow-up 1 day and 1 month after cataract surgery. Using app (WHOeyes) and a questionnaire at home or visit the clinic 1 week after cataract surgery.
Prospective, non-comparative, multicenter study on medical device with 12 months follow-up.
The objective of this study was to evaluate the clinical and patient reported outcomes after bilateral implantation of the AcrySof™ IQ Vivity™ Toric intraocular lens.
Direct comparison study between previous LASIK or non-LASIK cataract eyes, the performance between non-LASIK and LASIK patients were (i) Ophthalmic examinations: UDVA, CDVA and uncorrected near visual acuity (UNVA) (40cm) and (ii) Refractive prediction error: defined as difference between postoperative sphere and target refraction.
Cataract surgery is one of the most frequent surgeries carried out in the world. After cataract extraction an intraocular lens (IOL) is implanted in order to compensate for the crystalline lens power and correct patient's vision. In order to allow cataract extraction and IOL insertion, during the surgery a small incision is performed by the surgeon. This incision is performed using surgical knives, and a smaller incisión is associated with less postoperatory inflammation, faster corneal wound healing, and faster visual recovery. Several studies reported the importance of smaller incisions to reduce the risk of surgically induced astigmatism. In order to implant the IOL through this small incision, the IOL must be preloaded in a injector that allows introducing the IOL eficiently and consistently. The manual injector BIOLI manufactured by AST Products (model D), CE approved, is designed specifically to allow the IOL insertion safely, precisely, and controllably. Among the main characteristics of this delivery system is its design to minimize the incision size widening while inserting the IOL. The present retrospective study aims to provide more information with regards to the clinical efficacy of the BIOLI-D delivery system for the implantation of the trifocal Asqelio TFLIO130C IOL in patients submitted to cataract surgery. This will be assessed by analyzing the change in incision size after IOL implantation and the incidence of adverse events during and after the procedure.
In cataract surgery, the opaque lens is replaced by an artificial intraocular lens. The procedure also allows for correction of an refractive error such as myopia, hyperopia or astigmatism. In case of correction of an astigmatism, the axis intraocular lens has to be alligned to the axis of the corneal astigmatism. There are serveral options, the intendet position of the axis can be marked on the cornea, either manually using ink and a special caliper or with an automatic laser device. The aim of this study is to assess the accuracy of topography guided automatic marking of the intended IOL-axis in toric IOL-implantation in femtosecond laser assisted cataract surgery (FLACS)
Aim of this study is to assess whether a high-resolution scan of the crystalline lens before surgery may be helpful in predicting post-operative capsule bag diameter.
Aim:To determine the effectiveness and subjective satisfaction of patients with bilateral cataract surgery and implantation of intraocular lens (IOL) RayOne EMV with enhanced optic, using different degrees of mini-monovision (up to 0.74, between 0.75 -1.24 and 1.25-1.75). To compare individual groups between themselves . In particular, we would like to compare the independence of spectacle correction when looking into the distance, at medium distance and at reading distance.
Modern day cataract surgery isn't just a rehabilitative procedure anymore but rather aims at improving a patient's quality of life by reducing the need for spectacles in everyday life to a minimum. One way of achieving this goal is by using different lens technologies, such as a monofocal lens paired a lens with EDOF technology, as EDOF lenses provide an enhanced depth of focus by creating a single elongated focal point. As this "mix-and-match" is well established, the aim of this study is to compare the monofocal lens cohort to the EDOF lens cohort and evaluate visual acuity and patient satisfaction.
Modern day cataract surgery isn't just a rehabilitative procedure anymore but rather aims at improving a patient's quality of life by reducing the need for spectacles in everyday life to a minimum. One way of achieving this goal is by using different lens technologies, such as a mono- or bifocal lens paired a lens with EDOF technology, as EDOF lenses provide an enhanced depth of focus by creating a single elongated focal point. As this method is well established, the aim of this study is to compare the monofocal/EDOF cohort to the bifocal/EDOF cohort and evaluate visual acuity and patient satisfaction for both combinations.
