AIM:To investigate the findings of the eyes which were examined preoperatively by three mirror contact lens before the implantation of implantable collamer lens(ICL). To analysis the retinal pathological changes and to explore the clinical analysis of early diagnosis and treatment in retinopathy on fundus examination before operation.

METHODS:The retrospective case series study included 127 eyes of 64 patients who underwent phakic intraocular lens implantation were received the fundus examination by three mirror from April 2011 to April 2012 in our hospital. The age, refractive diopter, the findings of Goldmann three mirror examination and the condition of retinal photocoagulation were analysed and concluded.

RESULTS: A total of 34 eyes(26.8%)out of all 127 eyes(64 cases)were found to have peripheral retinal pathological changes. Eight eyes(6.3%)with retinal holes, 15 eyes(11.8%)with retinal lattice degeneration, 5 eyes(3.9%)with retina cream degeneration, 3 eyes(2.4%)with retinal paving stone degeneration,2 eyes with vitreoretinal adhesion and traction,1 eye(0.8%)with retinal hemorrhage. Twenty-five cases were given retinal photocoagulation and then received the ICL implantation after 3mo. The follow-up time was 1a. No retinal detachment happened.

CONCLUSION:Phakic before intraocular lens implantation for fundus examination by three mirror is contributed to find the peripheral retinal pathological changes and abnormity. And make the appropriate treatment before operation for improving the security of operation, it can also give help to the postoperative follow-up of the fundus of these patients.
