Comparison of stromal corneal nerves between normal and keratoconus patients using confocal microscopy.

Objective: To evaluate the differences in stromal corneal nerves between normal patients and keratoconus patients.

Material And Methods: A total of 140 eyes of 70 normal patients (group A) and 122 eyes of 87 keratoconus patients (group B) were examined with the confocal microscope, with a central scan of the total corneal thickness being taken. The morphology and thickness of the corneal stromal nerves were evaluated by using the Navis v.

Early confocal microscopy findings after cross-linking treatment.

Objective: To determine the effects of in vivo cross-linking treatment of the cornea.

Methods: Eighteen eyes of eighteen keratoconus patients underwent cross-linking treatment using a 0.1% riboflavin solution and ultraviolet A radiation at 370 nm at 3 mW/cm² for 30 minutes.

Epi-LASIK: a confocal microscopy analysis of the corneal epithelium and anterior stroma.

Background And Objective: To evaluate the confocal microscopy findings at the corneal epithelium and anterior stroma after epi-LASIK.

Patients And Methods: Twelve eyes of 12 patients underwent epi-LASIK. A central scan of the total corneal thickness was taken with the confocal microscope before and at 2 weeks and 1 month after surgery.

Support of the laboratory in the diagnosis of fungal ocular infections.

This is a retrospective, and descriptive study about the support that the laboratory of microbiology aids can provide in the diagnosis of ocular infections in patients whom were attended a tertiary-care hospital in México City in a 10-year-time period. We describe the microbiological diagnosis in palpebral mycose; in keratitis caused by Fusarium, Aspergillus, Candida, and melanized fungi; endophthalmitis; one Histoplasma scleritis and one mucormycosis. Nowadays, ocular fungal infections are more often diagnosed, because there is more clinical suspicion and there are easy laboratory confirmations.

How a femtosecond laser increases safety and precision in cataract surgery?

Purpose Of Review: To look at the recent applications of femtosecond laser (FSL) technology for capsulotomy and nuclear fragmentation in cataract surgery, the potential advantages, such as more precise and adjustable capsulotomies and the use of less phaco energy with this technology.

Recent Findings: The FSL can create incisions or spaces of different shapes, at a desired depth. This has started the application of the technology in the lens: after a clear image is taken of the lens through a previously dilated pupil, circular capsulotomy is done, with precision in shape and diameter, and in most cases, just needs to be grabbed, or requires very small use of the with the forceps.
