BACKGROUND Covering the eye of all snakes is a transparent integumental structure known as the spectacle. In order to determine variations in spectacle thickness among species, the spectacles of 217 alcohol-preserved museum specimens of 44 species belonging to 14 different families underwent optical coherence tomography (OCT) to measure spectacular thickness. Multivariable analyses were made to...

OBJECTIVE To examine the effect of spectacle correction of astigmatism during preschool on best-corrected recognition visual acuity (VA), grating VA, and meridional amblyopia (difference between acuity for vertical versus horizontal gratings) once the children reach kindergarten. DESIGN Comparative case series. PARTICIPANTS Seventy-three astigmatic (right eye > or =1.50 diopters [D] cylinde...

To improve visual and refractive outcomes, microkeratome-assisted lamellar keratoplasty for the treatment of keratoconus (exchange of a 9.0-mm anterior recipient lamella with a 9.0-mm donor lamella, using a 200-μm head for the former and a 300-μm head for the latter) was modified by adding a 6.5-mm incomplete full-thickness incision in the recipient bed before suturing the donor graft in place....

Purpose: To evaluate the efficacy of corneal cross-linking on keratoconic eyes in the pediatric age group. Setting: Private laser center, Haifa, Israel, affiliated to Hadassah Hospital, Jerusalem. Methods: This is a retrospective study of 29 eyes of 20 children treated with corneal cross-linking with aim to arrest the progression of keratoconus. We preformed collagen corneal cross-linking using...

METHODS: Prospective, nonrandomized study that included eight eyes of eight patients with concomitant endothelial disease and advanced cataract. In a first group of eight consecutive eyes, combined phacoemulsification, IOL implantation and DMEK were performed. Grafts were inserted with an ICL injector, encapsulated within viscoelastic plugs. Femtosecond laser-assisted descemetorhexis was perfor...

METHODS: Design: Retrospective interventional case series. Study population: 21 eyes from 21 patients who underwent visco-bubble technique for DALK, which involves the injection of ophthalmic viscosurgical devices (OVDs) into the deep stroma to form a visco-bubble to separate Descemet ́s membrane from the posterior stroma. Surgeries were performed between May 2010 and January 2013. Main outcome ...

Methods PTK was performed in 73 eyes of 64 patients. Data regarding the demography, indications for PTK, ablation depth, optical zone, keratometry. BCL removal , symptomatic relief, preand postoperative best spectacle-corrected visual acuity (BSCVA), spherical equivalent changes, recurrence and complications were analyzed. The indications for PTK in our study were classified into two categories...

Methods: We conducted a review of our initial 42 (19 with 6-month follow up) consecutive DSAEK surgeries using ASF tissue compared with 357 (199 with 6-month follow up) time-matched controls using standard tissue. Intraoperative and perioperative complications, including dislocations and primary graft failures, were compared. Six-month best spectacle-corrected vision, incidence of rejection epi...

Introduction: We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism. Case presentation: A 53-year-old woman had undergone toric implan...
