Title: A COMPARATIVE STUDY OF PHOTOREFRACTIVE KERATECTOMY BY USING PHOTOTHERAPEUTIC KERATECTOMY AND MECHANICAL METHOD
Abstract: Objective: To observe the symptoms,corneal epithelium healing and occurrence of haze after photorefractive keratectomy by using phototherapeutic keratectomy and mechanical method to remove corneal epithelium respectively.Methods: 122 patients(214 eyes) were selected from a group of patients with refraction ranging from-1.50D to-5.00D,who underwent photorefractive keratectomy by using phototherapeutic keratectomy and mechanical method to remove corneal epithelium.The patients was treated from Feb 2001 to Mar.2003.Results: The symptoms of patients after receiving photorefractive keratectomy by using phototherapeutic keratectomy was obviously less serious than by using mechanical method,corneal epithelium healing of the former was faster than that of the later,occurrence of haze of the former was 0,while the later was 5.Conclusion: The symptoms after photorefractive keratectomy by using phototherapeutic keratectomy was less serious,corneal epithelium healing was faster,and occurrence of haze was few.Phototherapeutic keratectomy is better than mechanical method.
