Filter by:The purpose of this study is to compare the subjective performance of comfilcon A lens against samfilcon A lens after 4 weeks of reusable lens wear.
The aim is to evaluate the short-term changes in ocular surface measures and tear inflammatory mediators after lenticule extraction (FLEx) and small-incision lenticule extraction (SMILE) procedures.
Two week, Open Label, randomized, bilateral, crossover, 1 week of daily wear in each combination (lens / disinfecting cleaning system).
This will be a 1-month dispensing, double-masked, randomized, contralateral study comparing the test lens against the control lens. The assignment of lenses to eyes (i.e. which lens type is to be worn in which eye throughout the study) will be selected according to a randomization table.
Two-month randomized trial comparing three groups.
The purpose of this study is to validate the safety and effectiveness of treating myopia (short-sightedness) higher than -10D using small incision lenticule extraction (SMILE) with the VisuMax femtosecond laser.
The excised ILM from 7 eyes of 7 patients with MTM including 7 eyes with macular retinoschisis and 4 eyes with foveal detachment but without any retinal break underwent vitrectomy with induction of posterior vitreous detachment and ILM peeling was examined to evaluate ultrastructure with electron microscopy.
The medical records of 16 eyes of 16 patients with macular hole retinal detachment or myopic traction maculopathy who received viterctomy including internal limiting membrane peeling and scleral shorting surgery were reviewed. Best-corrected visual acuity, axial length, retinal reattachment and macular hole closure, the shape of staphyloma determined by optical coherence tomography and 3-dimensional magnetic resonance imaging were assessed.
This was be a randomized, contralateral, double-masked, dispensing study comparing the Study test lens against the control lens over one month of lens wear. The study results were not used for design validation of test lens.
This will be a controlled and randomized, single-masked, crossover study in which 48 subjects will use the Biofinity Contact Lens (comfilcon A) with each of the two lens care products ('solutions'), (Synergi and Biotrue Multi-purpose Solution) for one month each. Follow-up visits for each solution will take place at one week, two weeks and four weeks: with a one-week 'wash-out' period between the solutions. Key outcome measures for this study include biomicroscopic and subjective responses to the lens/solution combinations.
