Purpose
To investigate the effect of topical pilocarpine on topical cycloplegia and on the results of refractive surgery.
Methods
The study included 100 eyes of 100 patients who underwent laser-assisted in situ keratomileusis. Group 1 comprised patients who wanted to undergo surgery on the same day after cycloplegic examination and were applied with 2% pilocarpine hydrochloride; group 2 comprised patients whose pupils spontaneously went into the natural position. Corneal thickness, mean refractive spherical equivalent (MRSE), uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), pupil diameter, pupil center shift and high-order aberrations (HOAs) were compared between the two groups.
Results
There were no statistically significant differences between the groups in respect of preoperative age, gender, corneal thickness, MRSE, UDVA and CDVA. The pupil diameter was not statistically significant between the groups. Pupil diameter after pilocarpine was not statistically significant when compared with the natural pupil diameter. There were no statistically significant differences in postoperative HOA between the two groups.
Conclusions
The pupillary dilatation and the associated pupillary shift were reduced with pilocarpine. Postoperative refractive values and aberrations showed no difference between the groups.
