This paper examines the preliminary effects of Excimer laser treatment on visual function in 15 patients who had myopia ranging from -1.75 to -6.00 dioptres.
The use of the Excimer laser to correct refractive error is discussed. Visual function was assessed using a Snellen’s acuity test as well as the Vector Vision CSV 1000 contrast sensitivity test. All tests were performed without and then with additional glare using the Mentor Brightness Acuity Tester (BAT). Visual function was assessed prior to Excimer treatment then post treatment at three months and the patients will be followed up again at six and 12 months. The visual function at three months post Excimer is discussed in this paper.
