Purpose

This study aimed to compare the thickness of conjunctival autografts  in pterygium surgery using the Moscovici dissection technique  with the
manual dissection and to  assess the difficulty of these techniques.

Setting

In this randomized clinical trial

Methods

Methods
 
 
30 eyes of 30 patients undergoing pterygium surgery were divided into :Moscovici dissection technique group (Air) and  manual dissection group
(MD). The patients were treated and evaluated at the Visão Laser Ophthalmological Hospital (Santos, São Paulo, Brazil). Optical coherence tomography
was performed to measure graft thickness three months postoperatively. Three images were obtained from each eye, and three measurements were taken at a distance of 1.5 mm perpendicular to the limbus in each capture. The surgeon graded the difficulty of obtaining the graft with the technique performed from 1 (lowest difficulty) to 4 (highest difficulty).

Results

We found statistically significant differences between the two techniques' difficulty and the mean conjunctival autograft thickness in the two groups (p = 0.01 and p = 0.05, respectively). The average difficulty rating for the Air group was 1.47, while that for the MD group was 2.20. The mean thickness of the three measurements was252 µ in the Air group and 298 µ in the MD group, with medians of 250 µ and 278 µ, respectively.

Conclusions

Our study showed that the Moscovici technique results in thinner grafts and can be performed with greater surgical ease.
