【Abstract】 Objective To investigate the safe and effective methods of surgical treatment of lens subluxation in Marfan syndrome. Methods 16 eyes of 8 cases suffered from Marfan syndrome and severe lens subluxation were treated in this way that small incision,“dryly” lens aspiration,posterior capsule and zonule keeping,and “dryly” vitrectomy when necessary,one haptics of the foldable intraocular lens fixed at ciliary sulcus,another haptics and the optic part of the intraocular lens put onto the remained lens capsule.The range of lens subluxation in all these eyes was more than 180 degree,and all the lens edge of the side of lens subluxation came to the area of pupil in nature condition.Best-corrected vision of 14 eyes was less than 0 3,another 2 eyes was 0 3 or better. Results All cases got obviously better postoperative vision.After operation,the uncorrective vision of 6eyes ranged from 0 1 to 0 3,and 10 eyes ranged from 0 4 to 0 9.The best-corrected vision of 4 eyes ranged from 0 1 to 0 3,and 12 eyes ranged from 0 4 to 0 9.The pupil was normal,the intraocular lens was in the correct situation and no one was disclining.There were no severe complication as corneal edema,high intraocular pressure,expulsive suprachoroidal hemorrhage,detachment of ciliary body and uvea,vitreous opacity and proliferation,retinal detachment,cystoid degeneration of macula and so on.14 eyes showed pupil is perfectly placed in normal location,2eyes showed slig ly elevated but not beyond the edge of the optic part of the intraocular lens. Conclusions The technique of small incision,“dryly” lens aspiration,posterior capsule and capsular zonular network keeping,“dryly” vitrectomy when necessary,one haptics of the foldable intraocular lens fixed at ciliary sulcus,another haptics and the optic part of the intraocular lens put onto the remained lens capsule,can be safely and effectively used to treat lens subluxation in Marfan syndrome.更多还原
