          Abstract

          OBJETIVO: Avaliar a qualidade de corte do microcerátomo Masyk® na confecção de lamela corneana pediculada em olhos frescos humanos provenientes de Banco de Olhos. MÉTODOS: Realizou-se estudo prospectivo no "Eye Clinic Day Hospital" (São Paulo, Brasil), com 20 olhos humanos frescos de Banco de Olhos. Utilizou-se o microcerátomo Masyk® para confecção de lamela corneana pediculada. A espessura programada foi 160 µm e o diâmetro programado de 9,5 mm em todos os olhos. As espessuras efetivas das lamelas foram aferidas pelo paquímetro P55, Paradigm, USA e os diâmetros verticais do leito estromal com compasso cirúrgico. RESULTADOS: Não ocorreram complicações durante a utilização do microcerátomo e não foram identificadas lamelas livres, perfuradas ou incompletas. A média das espessuras efetivas foi de 160,34±5,10 µm, com variação entre 149 e 181 µm. A média das medidas dos diâmetros verticais do leito residual foi de 9,64±0,16 mm, com variação entre 9,30 e 9,85 mm. CONCLUSÃO: O corte do microcerátomo Masyk® mostrou-se reprodutível, previsível e seguro em confeccionar lamelas corneanas pediculadas de espessura e diâmetros adequados em olhos humanos frescos de Banco de Olhos.

          PURPOSE: To evaluate the cut quality of Masyk® microkeratome in obtaining a corneal flap from human eyes of Eye Banks. METHODS: Prospective study with 20 human eyes from Eye Banks. All flaps were programmed to obtain 160 µm thickness and 9.5 mm diameter. The thicknesses were calculated with P55 pachymeter (Paradigm, USA), and diameter with compass. RESULTS: No complications were observed during the use of the microkeratome. The central corneal thickness average was 160.34±5.10 µm and range from 149 to 181 µm. The vertical diameter average was 9.64±0.16 mm and range from 9.30 to 9.85 mm. CONCLUSION: Masyk® microkeratome showed to be effective for obtention of corneal flap with appropriate thickness and diameter from human corneas of Eye Banks.

            Incidence and management of intraoperative and early postoperative complications in 1000 consecutive laser in situ keratomileusis cases.

            To identify intraoperative and early postoperative complications of laser in situ keratomileusis (LASIK) surgery learning curve and to offer recommendations on prevention and management. Retrospective noncomparative case series. The first 1000 consecutive myopic LASIK eyes (April 1995-February 1997) operated on by one surgeon (HVG) were examined. Myopic LASIK surgery was performed with the Chiron Corneal Shaper and NIDEK EC-5000 excimer laser. The preoperative and 6-month postoperative spherical equivalent, best-corrected visual acuity, and corneal status were recorded, as was the incidence of intraoperative and early postoperative complications. The rate of retreatments was also recorded. There were 32 (3.2%) intraoperative complications and surgical events recorded, including 19 (1.9%) microkeratome-related flap complications and 13 (1.3%) nonmicrokeratome-related surgical events such as inability to obtain sufficient suction. There were 18 (1.8%) postoperative complications requiring repositioning of microwrinkled or shifted flaps. Six-month spherical equivalent was -0.52 diopter [D] +/- 1.19 D for eyes with microkeratome complications, -0.56 D +/- 1.07 D for the group with nonmicrokeratome-related intraoperative events, and -0.78 D +/- 0.92 for eyes requiring postoperative flap repositioning. None of the 32 eyes with intraoperative complications and surgical events lost 2 or more lines of vision. One eye in the postoperative complications group lost two lines of vision. The rate of microkeratome complications related to surgical technique and the overall surgery times decreased over the course of the first 1000 myopic LASIK cases. The complications encountered during the early learning curve of LASIK surgery have not in this series resulted in a significant loss of best-corrected visual acuity. With increasing surgical experience, the incidence of complications, along with surgical times, has decreased.
