Myopic photorefractive keratectomy in eyes with atypical inferior corneal steepening.

Purpose: To evaluate the visual and refractive results of photorefractive keratectomy (PRK) in eyes with atypical inferior corneal steepening (AICS).

Setting: Department of Ophthalmology, Hôpital Morvan, University of Breast, France.

Methods: Using videokeratopography, we screened 310 eyes that had PRK from November 1992 through November 1993 and found that 35 eyes exhibited topographic patterns consistent with AICS with no clinical findings.

Excimer laser photorefractive keratectomy to correct astigmatism.

Purpose: To evaluate the efficacy of excimer laser photorefractive keratectomy (PRK) to correct astigmatism.

Setting: Hôpital Morvan, Brest, France.

Methods: A 193 nm excimer laser was used to perform toric ablation with an expanding slit to flatten the cornea in the steeper meridian and/or to correct myopia with an iris diaphragm in 72 eyes (55 patients): 68 eyes for compound myopic astigmatism and 4 for astigmatism only.

Clinical results of excimer laser photorefractive keratectomy: a multicenter study of 265 eyes.

Efficacy, predictability, and safety of excimer laser photorefractive keratectomy were evaluated at centers in Paris and Brest, France. Photoablation was performed with the VISX laser on 265 eyes (151 at the Paris center and 114 at the Brest center). The eyes were clinically and statistically evaluated over a six month follow-up.

[Neuropapillitis in Behçet disease. A case].

The authors report the case of a 34 year old woman, who developed acute neuropapillitis, which appeared to be the first ophthalmologic manifestation of Behçet's disease. One year later, this patient recurred with another neuro-ophthalmologic sign: a sixth nerve palsy.

[Corneal endothelium in uveitis].

The authors report the results of a prospective study concerning corneal endothelium during uveitis. They compared 65 patients (87 eyes) suffering from uveitis (divided into four groups: anterior uveitis, pars planitis, posterior uveitis, total uveitis) with a control group (36 eyes, same age). The results showed a decrease of the endothelial cell counts in the uveitis group.

[Treatment by refractive photokeratectomy of undercorrections after radial keratotomy].

Unlabelled: Residual myopia after radial keratotomy is one of the major problems of this technique, it may be corrected with laser keratectomy.

Materials And Methods: We present the results of nine eyes treated with photorefractive keratectomy, due to undercorrection after radial keratotomy. The photoablation was performed with the laser VISX 20/20, wavelength 193 mm, and concerned a residual spherical equivalent myopia (after RK) with an average of -2.
