Clinical observation of sub-bowman's keratomileusis for treatment of myopia

Objective: To observe the clinical effect of sub-bowman's keratomileusis(SBK) for treatment of myopia,and discuss its application value.Methods: A retrospective from January 2010 to September in our hospital of 71 cases(133eyes) underwent the treatment of myopia by SBK,to analyze the postoperative uncorrected visual acuity,refraction,tear film break up time(BUT),complications,etc.Results: Postoperative 1 week the eyes of UCVA equal to or better than 0.5 are 133(100%),≥ 1.0 are 131(98.5%);postoperative 1 week diopter ≤ ± 0.5 with 112 eyes(84.2%),≤ ± 1.0 with 129 eyes(97.0%);postoperative 3 months BUT is 14.42 ± 3.24,basically returned to preoperative levels,after 3 and 6 months compared with the preoperative was no significant difference(P 0.05);11 eyes(8.3%) with flap edge bleeding,5 eyes(3.8%) had a small amount of epithelial implantation beneath the corneal flap,corneal flap slightly wrinkled,local mild interlayer keratitis reaction,and processed corneal still were transparent.Conclusion: The treatment of myopia by SBK is safe,effective,and predictable,with good clinical value.
