[Corneal incision in inverse step (author's transl)]

The author presents a corneal incision similar to that of Charleux, but the "biseau" was replaced by a step. Thus the wound is easier closed by the intraocular pressure because the thin posterior plane is moulded over the irregularities of the superficial plane easier than the short slope of Charleux's incision. As a proof, without reducing the postoperative security, the suture consists only of 3 points -- thus inducing a favourable influence on the cicatrisation --, the knotting force is diminished -- avoiding thus the risk of thread cutting the tissue, and the conjunctival covering is rarely used -- leaving thus the entire draining way of the aqueous humour unaffected. The 80 patients operated on left the hospital in the 4th day (41%), 10th day (50%) or in the 14th-21st day (9%), with satisfactory late results: visual acuity superior to 5/10 (87%) and astigmatism inferior to 1D (89%).
