The corneal sensibility was examined with the aesthesiometer of Draeger in 41 patients after refractive corneal surgery, 31 patients after radial keratotomy, 5 after epikeratophakia, 5 after excimer laser ablation. It could be shown that after radial corneal incisions the sensibility remains normal. After epikeratophakia the corneal sensibility is asensible even 3 years after operation. The lenticle periphery shows an increase of sensibility after 6 months. Excimer patients with "haze" showed a significant hyposensibility in the centre. The central sensibility showed normal values after a normal corneal wound healing.

This paper presents data on 30 phakic eyes with primary open-angle glaucoma treated by argon laser trabecular surgery (Wise's technique). Mean intraocular pressure was reduced from 27.8 mm Hg to 18.3 mm Hg. The mean observation time was 7.2 months. Therapy failed in 3 cases of pigmentary glaucoma. There were no appreciable complications.
