Posterior Corneal Surface Stability after Femtosecond Laser-Assisted Keratomileusis.

The purpose of this study was to evaluate posterior corneal surface variation after femtosecond laser-assisted keratomileusis in patients with myopia and myopic astigmatism. Patients were evaluated by corneal tomography preoperatively and at 1, 6, and 12 months. We analyzed changes in the posterior corneal curvature, posterior corneal elevation, and anterior chamber depth.

Influence of pseudophakic lens capsule opacification on spectral domain and time domain optical coherence tomography image quality.

Purpose: To evaluate the influence of posterior capsule opacification (PCO) on optical coherence tomography (OCT) acquisition of macular retinal thickness (RT) and volume using time domain OCT (TD-OCT) and spectral domain OCT (SD-OCT).

Materials And Methods: We studied 37 eyes of 31 patients with PCO. Each patient underwent an evaluation with TD-OCT and with SD-OCT before and after Nd:YAG capsulotomy.

Ocular penetration of topical antibiotics: study on the penetration of chloramphenicol, tobramycin and netilmicin into the anterior chamber after topical administration.

Background: To compare penetration in the aqueous humour of topically applied antibiotics.

Design: Randomized prospective study, Department of Ophthalmology, University of Perugia, Italy

Participants: Patients undergoing cataract surgery.

Methods: One hundred twenty-two patients were included: 14 received one drop of chloramphenicol suspension; 12 one application of chloramphenicol gel; 11 one drop of netilmicin suspension; 13 one drop of tobramycin suspension; 37 repeated instillations of chloramphenicol suspension every 10 min for a total of four drops; and 35 repeated instillations of chloramphenicol gel every 10 min for a total of four drops.

Macular thickness measured by optical coherence tomography in a healthy population before and after uncomplicated cataract phacoemulsification surgery.

Purpose: To examine macular changes before and after uncomplicated cataract surgery in a healthy population.

Material And Methods: In a prospective study, we evaluated 62 eyes of healthy patients having elective cataract phacoemulsification. We performed optical coherence tomography (OCT) measurements preoperatively and at 3, 6, 12, 20, and 28 weeks after surgery.
