Filter by:To evaluate the improvement in myopic refractive error and the corneal endothelial safety with a corneal crosslinking treatment regimen for mild myopia. The treatment involves a 4-mm central treatment zone in high oxygen environment without corneal epithelial debridement.
this is an interventional prospective clinical study which was conducted to evaluate the efficacy, safety, predictability, ocular aberrations, and flap thickness predictability of Visumax femtosecond laser (FSL) compared to Moria M2 microkeratome (MK) in mild to moderate myopia.
This project aims to study the effects of treatment characteristics on myopia control in orthokeratology by investigating the effects of modified treatment zone by reducing the lens back optic zone diameter on the effect of myopia control. The project will be a two-year randomized, double-masked (examiner - mask axial length only) study conducted at The Hong Kong Polytechnic University recruiting sixty Chinese subjects aged between 6-11. Subjects will be randomly assigned to two ortho-k groups. The Control group will wear KATT BeFree lens with a BOZD of 6mm while the Test group will wear KATT MC lens with a modified BOZD of 5mm.
From July 2015 to December 2015, clinical record of 8 consecutive cases of macular hole with retinal detachment in high myopia treated with combined inverted and free ILM flap insertion into the hole were retrospectively reviewed. The anatomical and function outcomes were assessed.
Atropine eye drops are increasingly prescribed for the management of progressive myopia or short-sightedness. A previous study suggested that the back of the eye or choroid may be a part of the mechanism by which it induces its effects. The aim of this study is to characterize the effects of atropine on choroidal thickness and the influence of time of administration (am vs pm). It is hypothesized that the atropine's effect on choroidal thickness will vary with baseline thickness related to diurnal rhythm, where thicker baseline thickness will show a reduced choroidal response.
A prospective study included 20 patients with super high myopia who underwent bilateral uneventful cataract. 360°anterior capsule polishing was performed with double-ended capsule polisher randomly in one eye, and the opposite unpolished was used as the control. The refractive state and size of anterior opening were measured at postoperative 1 day as the baseline. Then they followed up at 1 month, 3 months and 6 months after surgery to record refractive state, higher-order aberrations, size of anterior opening, tilt and decentration of IOL (intraocular lenses)and PAD(postoperative aqueous depth). The paired t test was used to compare the differences between the two groups, and the same test the postoperative follow-up comparing with the baseline.
The objective of this study is to demonstrate that the OxyAqua silicone hydrogel soft contact lens could be prescribed as a supportive care for myopes.
The purpose of this study is to evaluate the clinical performance and subject's preference out of three LRE (Limbal Ring Enhancing) lens types: etafilcon A (Johnson&Johnson), methafilcon A (Interozzo), and methafilcon A (CooperVision).
The aim of this non-dispensing fitting study is to evaluate the short term lens fit, vision performance of three monthly replacement sphere lenses.
This research project intends to observe patients with high myopia who show pathological retinal changes, in order to evaluate more data on the risk factors for developing mCNV within this research project population in Germany.
