Abstract Details

Purpose:

The aim of this study was to evaluate the safety and efficacy of asteroid hyalosis removal by anterior vitrectomy through posterior capsulorhexis during phacoemulsification.

Setting:

Sohag University Hospital

Methods:

The study was conducted on 16 cataractous patients associated with asteroid hyalosis. Phacoemulsification was performed followed by removal of the asteroid hyalosis through posterior capsulorhexis by anterior viterctomy and before intraocular lens implantation. Patients were examined one day, one week, one month, three months and six months postoperatively. Data were analyzed using paired t-tests to compare the preoperative and postoperative uncorrected visual acuity(UCVA) and corrected visual acuity(DCVA). The basic postoperative parameters at each follow-up visit were assessment of UCVA and DCVA and slit-lamp examination to evaluate the corneal condition and to detect any postoperative inflammation..

Results:

All patients in this study showed statistically significant improvement in postoperative visual acuity (p=0.001) at the last follow-up visit. One patient who had diabetic retinopathy and maculopathy showed deteriorated visual acuity at the last postoperative visit (P=0.2). Two patients had suboptimal best corrected visual acuity after six months due to the presence of cellophane maculopathy detected clinically and by OCT examination (P=0.01).

Conclusions:

removal of asteroid hyalosis by anterior vitrectomy during phacoemulsification through a posterior capsulorhexsis is safe and effective and enables the surgeon to treat undiagnosed missed retinal lesions that were not obvious preoperatively.
