Abstract Details


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.


Hospital Oftalmológico de Sorocaba, São Paulo, Brazil.


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.


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).


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