Phacofragmentation without perfluorocarbon liquid for dislocated crystalline lenses or lens fragments after
1Eye Center, Second Affiliated Hospital of Zhejiang University, Hangzhou, China. zuashecy@public.Hz.zj.cn
Purpose:
To evaluate the clinical outcome of vitrectomy with phacofragmentation without perfluorocarbon liquid (PFCL) in the management of dislocation of the crystalline lens, caused by trauma, hereditary disorders, or hypermature cataracts, and lens fragments due to phacoemulsification.
Methods:
A prospective study was conducted to evaluate 30 eyes of 29 patients who had undergone standard pars plana vitrectomy with phacofragmentation without PFCL in the vitreous cavity, for the removal of dislocated crystalline lenses or lens fragments, from January 1998 to July 2000. All cases were followed for more than six months.
Results:
Final best corrected visual acuity of 0.5 or better increased from 0% preoperatively to 36.7% postoperatively, and 0.2 or better rose to 76.7%. The mean IOP was significant reduced, from 26.35 mmHg to 12.75 mmHg. No intraoperative complications occurred. Although two eyes (6.7%) developed retinal detachment, one (3.3%) had cystoid macular edema (CME) and one (3.3%) had a transient intraocular pressure increase (to 25 mmHg) postoperatively, all others had a favorable outcome.
Conclusions:
Standard pars plana vitrectomy with phacofragmentation without PFCL in the vitreous cavity is a safe, simple, and effective method for removing a dislocated crystalline lens or lens fragments, with good visual outcome.
