a dosage of 50 mg/d for 3 days. There was no recurrence of epithelial ingrowth or diffuse lamellar keratitis. Culture results remained negative. All sutures were removed on postoperative day 11. The prednisolone was tapered, and the ofloxacin treatment was discontinued. At postoperative month 8, there was mild interface haze (Figure 3). In the affected eye, the uncorrected visual acuity was 20/...

Microkeratome-assisted anterior lamellar keratoplasty has emerged as a surgical option for conditions affecting the clarity of the outer 200 mum of the cornea. Herein we describe the outcome of a simple procedure in which the excimer laser can be used to augment deep tissue removal after both recipient bed and donor graft are prepared with the microkeratome. Our noncomparative interventional ca...

A 50-year-old woman had implantation of intrastromal corneal ring segments for recurrent keratoconus 15 years after penetrating keratoplasty. Two segments (0.15 mm and 0.25 mm) were inserted without any intraoperative or postoperative complications, using the femtosecond laser to create the tunnels (superior and inferior). Ten months after the procedure, the uncorrected visual acuity was 20/100...

A 42-year-old man had Intacs (Addition Technology Inc.) implantation for early pellucid marginal degeneration (PMD). Two Intacs segments (0.45 mm thickness) were inserted uneventfully in the fashion typically used for low myopia correction (nasal-temporal). Eleven months after the procedure, the uncorrected visual acuity was 20/200, compared with counting fingers preoperatively, while the best ...

WITH a correctly fitting pair of approximately -14 D. corneal contact lenses, a person with normal emmetropic eyes can become a 12 D. experimental hyperope, and he can very nearly simulate the exact type of vision of the spectacle-corrected aphakic by wearing a correctly fitted set of + 12-00 D. Sph. cataract spectacle lenses. With this "simulator of aphakia", the inquisitive scientific researc...

The measured values of the axial meridional powers for 311 spectacle lenses are reported. The spherical refractive powers range from + 7 . 0 0 to —20.00 diopters with cylindrical powers of 0.00, 1.00, and 2.00 diopters. The departures of the measured from the nominal values are shown. The probable errors of measurement are discussed. A set of tolerance values is suggested and the degree of comp...

PURPOSES To evaluate the optical performance of blue-light filtering spectacle lenses and investigate whether a reduction in blue light transmission affects visual performance and sleep quality. METHODS Experiment 1: The relative changes in phototoxicity, scotopic sensitivity, and melatonin suppression of five blue-light filtering plano spectacle lenses were calculated based on their spectral...
