Myopic PRK may lead to long-term impairment of mesopic vision, while soft contact lens use does not seem to markedly influence mesopic vision in eyes with low to moderate myopia.

This study suggests that contact diode laser cyclophotocoagulation is an effective method and a valid alternative to cyclocryocoagulation in the treatment of refractory glaucoma including congenital glaucoma.

Laser keratomileusis is a laser-specific procedure whereby a layer of corneal tissue as thin as 10 µm or more is removed from the anterior surface. In most cases, the laser ablates not only Bowman's layer but also portions of the anterior stroma. The histologic evaluation presented shows that the ablation behavior of these two layers is not uniform: at a fluence of 205 mJ/cm p 2 in Bowman's layer, the ablation rate was 0.38 ± 0.05 µm per pulse, whereas in stroma it amounted to 0.55 ± 0.1 µm per pulse. In epithelium, the ablation rate was 0.68 ± 0.15 µm per pulse, but decreased with deeper excisions. We discuss the consequences of these different ablation rates on the procedure of laser keratomileusis. [Refractive and Corneal Surgery 1990; 6:99-102.]

The authors show that with the Excimer laser partial trabeculectomy can be performed, a procedure in which the juxtacanalicular meshwork is removed while the other layers remain untouched. It was proved in experiments on ten enucleated human eyes that at most 3% of the outflow resistance is localized in the uveal and sclerocorneal meshwork. The clinical applicability of partial trabeculectomy was demonstrated on five eyes.
