Abstract Details

Purpose:

The purpose of this study is to know if the use of contact lenses can cause alterations in number, size, shape, and variation of the corneal endothelial cells.

Setting:

Clínica de Ojos Ruiz-Montenegro & Eurolaser Ocular Morelia, Michoacán México.

Methods:

We carried out a descriptive study using non contact specular microscopy CSO Italy Model SP01 Equipment. 50 eyes of 25 patients, 17 ♀ y 8 ♂ Age range (22-63) average 25 years old. Inclusion criteria: Healthy eyes, soft contact lens (SCL) wearers and rigid contact lens (RCL) wearers for more than 8 years, and at least 8 hours daily We included 3 groups, wich were compared each other. Group 1 SCL wearers Groups 2 RCL wearers Control Group: Patients who have never worn contact lenses Statistical Analisys was perform with ANOVA (Analisys of variation)(p < 0.05).

Results:

We found a significant lower values in cell density/mm2 in both groups (soft and rigid) and higher values in polymegathism compared with the control group. (p < 0.05) The SCL wearers had an average of 2062 cell density/mm2 compared whit 2359 cell density/mm2 in control group, and 28% in polymegathism compared whit 14% in control group. The RGP wearers had an average of 1920 cell density/mm2 compared 2374 cell density/mm2 in control group, and 36% in polymegathism compared with 14% in control group.

Conclusions:

•We found a statistically significant lower values in cell density/mm2, and higher values in polymegathism in both groups , SCL and RCL wearers compared with the control group. ( p < 0.05) •We suggest to decrease the daily time, wearing contact lenses. •We also strongly recommend to perform a specular microscopy in contact lens wearers for more than five years, particularly if the patient is considering a refractive surgical procedure, instead of keep wearing contact lenses.
