Abstract Details

Purpose:

To determine the effect of upper blepharoplasty on corneal tomography using Galilei® and ocular biometry with IOLMaster®, in order to access the better timing for blepharoplasty and cataract surgery.

Setting:

Hospital Oftalmológico de Sorocaba, São Paulo, Brazil.

Methods:

Prospective, nonrandomized, observational study performed from May 2014 to March 2015. Only patients submitted to upper blepharoplasty were included. Patients with corneal and/or macular pathology, glaucoma, history of ocular or palpebral surgery, more than 6 diopters (D) of ammetropia and/or best corrected visual acuity worse than 20/40 were excluded. Corneal tomography with Galilei® and ocular biometry with IOLMaster® were performed before surgery and at months 1 and 6 postoperatively. Primary outcome measures included steep simulated keratometry (simK), flat simK, astigmatism, axis, and intraocular ocular lens (IOL) diopter using Holladay’s formula for emmetropia. Paired t-test was used for statistical analysis.

Results:

36 eyes from18 patients (14 females, 4 males), aged from 47.8 to 74.7 years (mean 58.6 years) were included in the study. Statistical analysis at 1 month (partial results) postoperatively showed no change on corneal steep simK (45.22 D to 45.23 D), flat simK (44.49 D to 44.46 D), astigmatism (0.73 D to 0.77 D) and astigmatism axis (90.3° to 83.6°) before and after surgery (p > 0.05 for all comparisons). Moreover, no significant change was found on IOL calculation (22.9 D to 22.8 D).

Conclusions:

There were no significant changes found on corneal tomographic parameters using Galilei® nor ocular biometry changes with IOLMaster® 1 month after upper blepharoplasty.
