ABSTRACT

Purpose: Find aberrometric changes induced by lubricant gel.
Methods: We studied patients younger than 40 years with refractive errors. Wave front analysis was done before and after application of hydroypropylmethylcellulose; measurements were repeated 1, 5, 15 and 30 min after application of gel. These patients also formed the control group.
Results: Eight women and 7 men were included (30 eyes); mean age 29 ± 4.78 years (range 21 to 37 years). High order aberrations increased after lubricant application, except defocus. Match decreased after gel application.
Discussion: Tear film is an important component of the ocular optic system; film changes also generate modifications in such system. Changes induced by lubricant gel must be considered when planning photorefractive surgery.
