Abstract: A Systematic Review of Studies Comparing Efficacy and Complications among Various Spacer Grafts in the Treatment of Lower Eyelid Retraction

RESULTS: Complete or near complete correction of ptosis (degree of ptosis<1mm) was achieved in all the 5 eyelids in postoperative follow-up. The preoperative MRD1 ranged from -4 to 0 mm with the mean of -3 mm while the postoperative ranged from 2.5 mm and 3.6 mm with a mean of 3.2 mm. The width of tarsal plate to excise ranged from 1.5 mm to 2.0 mm with a mean of 3.52 mm. The preoperative lid slit distance ranged from 0mm to 6 mm with a mean of 3.52mm while the postoperative ranged from 8 mm to 10.1mm with the mean of 8.8 mm. The most common complication was lagophthalmos. Immediate postoperative lagophthalmos was transient in all cases and were recovered to normal within 4 weeks.
