[Corneal astigmatism after tunnel incision for cataract extraction].

PURPOSE: To evaluate the development of astigmatism after cataract extraction depending on the kind of incision MATERIAL AND METHODS: Astigmatism was examined in 107 eyes of 92 patients, who underwent cataract extraction, mostly with IOL's implantation. In 52 eyes phacoemulsification with tunnel incision, measuring 5 mm in 27 and 8 mm in 25, was performed. In the control group of 55 eyes incision with scleral flap measured 2/5 of the corneal circumference. In cases with 5 mm incisions no sutures were used, in 8 mm incisions wounds were closed with single sutures and in control group the double continuous sutures were applied. Astigmatism was measured in two days, one week, four weeks and 3 months after surgery. RESULTS: Post-operative astigmatism decreased gradually and after 3 months was average 0.14 D in the eyes without sutures, 0.68 D in those with single ones and 1.78 D in the control group.

[Intraoperative prevention of bleeding into the anterior chamber in hemorrhagic glaucoma using viscoelastic substances].

The anterior chamber tamponade with Healon and 2.5% solution of hydroxymethyl-cellulose has been applied in 10 patients, aged 9-65 years, during antiglaucomatous surgery connected with interscleral dislocation of iris. The tamponade prevented the rupture of blood vessels of iris. Bleeding connected with the cutting of blood vessels was stopped by filling the anterior chamber with viscoelastic substance under increased pressure. It was possible to preserve the anterior chamber during surgery. The properties of Healon and 2.5% solution of hydroxymethyl-cellulose were similar.

[Comparison of the results of simultaneous trabeculectomy and cataract extraction with microscopic evaluation].

The dependence of hydrodynamics on the topography of trabeculectomy performed simultaneously with cataract extraction was checked in 35 eyes with cataract and glaucoma. The eye was opened by a three-surface incision with a broad scleral flap. The specimen were examined in a microscope. In 21 eyes the whole trabeculum together with Schlemm's canal were excised, in 12 eyes the anterior band. In the specimen from 2 eyes no elements of the trabeculum could be found. The dependence of the regulation of the IOP on the geography of the trabeculectomy was established. Accepting the filtering mechanism of the trabeculectomy one may assume that the applied method of incision promotes the formation of the outflow++ ways of the aqueous in a high percentage of cases.

[Reflections and conclusions after evaluation of 100 cases of phacoemulsification following the introduction of this method].

Presented are the difficulties encountered by the surgeon during the self-dependent acquiring of practical skill of cataract extraction by means of phacoemulsification. The observations were made in the course of performance of one hundred operations. The most frequent causes of failure and complications accompanying the first operations are cited. Attention is called to the tractability of the lenses to phacoemulsification in dependence of the property of the lens. These properties should be taken under consideration by the surgeon familiarizing himself with phacoemulsification in selection of cases for surgery. According to the author the acquiring the skill for phacoemulsification needs an adequate mastering of ocular microsurgery and the help of a surgeon who is familiar exactly with the secrets of this method.

[Surgery for pterygium with transplantation of an epithelial conjunctival flap. I. Methods].

Advantages and disadvantages as well as the efficacy of the most frequently applied surgical and combined methods of the pterygium therapy are discussed. A personal approach is presented; it consists of excision of the pterygium with a margin of a healthy tissue exposing the sclera and of covering of the conjunctival defect with a free epithelial layer of the bulbar conjunctiva from the upper quadrant. In case of necessity the flap may be used for a simultaneous reconstruction of the semilunar fold. The description of the method is completed by illustrations.

[Surgery for pterygium with transplantation of an epithelial conjunctival flap. II. Results of methods application].

The authors performed 41 operations of pterygium with transplantation of a free epithelial flap from the bulbar conjunctiva in order to cover the defect after the removal of the pathological tissue. The results of 35 operations had been controlled in the period of one to ten years. In 25 cases the operation was the first intervention, in 9 cases the second or third in a recurrent pterygium treated by other methods. In case of necessity the semilunar fold was reconstructed. A recurrence took place in one case after 6 months. The cause of the recurrence was the collection of the flap together with the fibrous layer of the conjunctiva. In the remaining cases a good and lasting effect was achieved, as well from an anatomical as from a cosmetic point of view. The results were compared with the results achieved by various authors by means of another methods.

[Late results of intrascleral peripheral iridencleisis].

Intrascleral peripheral iridencleisis was performed in 50 eyes with primary glaucoma in persons aged 41-71 years. The results of operation were evaluated after 5-10 years. The intraocular pressure did not exceed 21 mm Hg in 88% of eyes after the surgery alone and in 4% after an additional topical treatment. Regulation of the IOP down to 22 mm Hg was kept after surgery in 94% and after an additional treatment in 4% of the eyes. The mean coefficient of the aqueous outflow increased from 0.08 before surgery to 0.18 after it. Complications connected with the surgical procedure were scarce and negligible.
