Abstract:
PURPOSE: To evaluate the performance of Automated Corneal Shaper(R)(ACS) METHODS: we analysed the changes in intraocular pressure, axial length and corneal thickness and its influence on corneal flap following keratectomy by ACS in 20 porcine eyes. RESULTS: Corneal flap was made by ACS with plate 160, and its size and thickness were measured. With the suction ring application, intraocular pressure rised from 17.0 +/-1.96 mmHg to 62.0 +/-11.8 mmHg (p=0.001), while corneal thickness and axial length were decreased from 1090 +/-75.1 micro meter to 1074 +/-73.7 micro meter(p=0.001) and from 19.94 +/-0.89 to 19.72 +/-0.73 mm (p=0.028) respectively. Thickness of corneal flap was 122 +/-23.9 micro meter and its diameter was 8.3 +/-0.15 mm in average. CONCLUSION: special attention is required during LASIK (laser in situ keratomileusis) with Automated Corneal Shaper(R) in order to prevent intraocular damage by abrupt rise in intraocular pressure and change of eyeball contour.
