Complications of intraocular lens surgery.

Complications of cataract surgery and intraocular lens implantation are increasingly rare. New problems are emerging with foldable intraocular lenses. This annual review gives importance only to documented complications published during the last 14 months. Older complications can still be observed and the reader is referred to our last two articles in this journal, which are still fully valuable (Lebuisson and Weiser, Curr Opin Ophthalmol 1993, 4:75-82 and Lebuisson.

[Opinion of patients on the functioning of an ophthalmologic surgical outpatient center within a hospital. Analysis and consequences].

GOAL: The purpose of this analysis is to appreciate the patients perception of ambulatory cataract surgery performed in an out patient center localized inside a public hospital. MATERIAL AND METHODS: An anonymous postal questionnaire was designed to cover the aspects of ambulatory surgery which could influence the patients perception. 576 patients were included and the study collected 487 answers to 12 questions. Authors give attention to the pros and cons detected during the study time. RESULTS: The key question shows that most patients recommend this procedure as the treatment of choice. The percentage increases with surgical experience of surgeons: the response rate to the questionnaire was both rapid and impressive. Final visual acuity did not influence significatively the overall perceptions of patients. CONCLUSION: Answers to the 12 questions point of importance of information, coordination and preparation. A high level of surgical and anesthetic formation is required to obtain an easy out patient ambulatory procedure.

[Local anesthesia for cataract surgery in adults. Retrospective study of peribulbar, subconjunctival and topical anesthesia].

PURPOSE: A retrospective analysis of 4 methods of local anaesthesia for adult cataract surgery compares the efficiency of: peribulbar anaesthesia injection, subconjonctival anaesthesia injection, both of these techniques and eye topical anaesthesia. No sedation is used. All patients are classified in ASA I or ASA II grade of the anaesthesiologist classification. All the surgeries are performed in an out patient center. The anaesthetic solution combines equally bupivacaine 0.5%, lidocaine 2% and hyaluronidase 250 UI. Phacoemulsification is performed through a scleral small incision. METHODS: 390 patients are separated in 4 groups. Analgesia and Akinesia are evaluated in 3 levels: total, partial and absent. RESULTS: They show that a single peribulbar injection less of 8 ml is sufficient in 86.5% of cases. In case of a unique subconjonctival injection 2 ml are used with a rate of full success of 67.8%. When combining these 2 methods the surgery is easily possible in 97.9% of cases. A complementary subconjonctival injection is necessary in 4.9% of eyes receiving only the inferior peribulbar infiltration and in 13% of eyes anaesthezied by the single subconjonctival injection. 20.3% of eyes receiving only topical anaesthesia need a complementary subconjonctival injection during surgery. But the study covers the first series of patients operated with this new method, most of these cases are men. Results are better with experience, confidence and corneal incision. CONCLUSION: Local anaesthesia is a safe procedure offering very few local and general risks. General sedation or premedication is not necessary. The choice depends on the akinesia factor which is far more difficult to obtain with so few anaesthetic volumes than the analgesia.

[Ambulatory ocular surgery].

Out-patient ocular surgery exists in numerous countries and is currently making its debut in France. The authors note, from a series of 286 out-patients lens implantation operations, that the rate of complications does not significantly differ from that of in-patient procedures. These figures corroborate the results published in the United-States. The procedures applies only to motivated patients in good health and non-handicapped who well understand instructions. The selection of patients is done with the concurrence of the anesthesiologist. The anesthesia is local, occasionally preceded by a suitable sedative. The procedure takes place in an adapted surgical center of which there are several types. The check-out of the patient is within one to four hours after the operation. The constraints posed by equipment and facilities are significant since the responsibility dwells at all times with the surgeon. Caution must be exercised in all phases. The economic advantages of out-patient ocular surgery are not obvious in the current managerial context all the more so because the investment (in equipment and facilities) is costly. Nonetheless, a desired positive secondary effect would be the freeing of hospital beds for other uses. As a parallel, out-patient ocular surgery responds to a new patients demand to be treated rapidly and in an up-to-date manner (both medically and in terms of reception, waiting periods and check-out). The quality of the all procedure is increased.

[Treatment of senile macular degeneration with Ginkgo biloba extract. A preliminary double-blind drug vs. placebo study].

Senile macular degeneration is a frequent cause of blindness for which there is no satisfactory medical treatment. A double-blind trial comparing Ginkgo biloba extract with a placebo was conducted in 10 out-patients at the Hôpital Foch. Drug effectiveness was assessed on the results of fundoscopy and of measurements of visual acuity and visual field. In spite of the small population sample, a statistically significant improvement in long distance visual acuity was observed after treatment with Ginkgo biloba extract. The assumed pathogenesis of senile macular degeneration is discussed with emphasis on free oxygenated radicals.

[Cicatricial ectropion and lamellar icthyosis (author's transl)].

The authors describe the surgical procedure employed in a case of bilateral cicatricial ectropion (superior and inferior), occurring during the course of a lamellar icthyosis. Total skin homografts should be applied before the appearance of severe corneal lésions on both eyelids, inferior and then superior. Two factors have to be emphasized: the apparent appearance of rejection of the grafts when the first dressings are made, and the progressive retraction of the homografts which requires repeated graft applications.
