Purpose: To determine the effect of upper blepharoplasty on corneal topography and intraocular lens power calculation using Galilei and IOLMaster., Methods: Thirty patients submitted to upper blepharoplasty from May 2014 to March 2017 at the Hospital Oftalmológico de Sorocaba (São Paulo, Brazil) were included in this observational case series. All patients underwent imaging sessions with Galilei and IOLMaster preoperatively (baseline) and at 1 and 6 months postoperatively. Primary outcome measures using both devices included flattest, average, and steepest corneal curvature, corneal astigmatism, and blepharoplasty-induced corneal astigmatism. Determination of axial length and lens power calculation were performed using only IOLMaster (Holladay formula). Paired t-test and vectorial analysis were used for statistical analysis., Results: Sixty eyes from 30 patients were prospectively included. Vectorial analysis showed that 6 months after surgery, blepharoplasty induced on average 0.39 D and 0.31 D of corneal astigmatism, as measured with Galilei and IOLMaster, respectively. IOLMaster measurements showed that average corneal curvature (44.56 vs 44.64 D, p=0.01), steepest corneal curvature (45.17 vs 45.31, p=0.01) and corneal astigmatism (1.22 vs 1.34, p=0.03) were higher 6 months after surgery. IOLMaster measurements also showed that intraocular lens power was significantly smaller 6 months after surgery (22.07 vs 21.93, p=0.004). All other parameters showed no change for comparisons between baseline and 6 months (p>0.05 for all comparisons)., Conclusion: Upper eyelid blepharoplasty influenced intraocular lens calculation using the IOLMaster. However, the influence was not clinically significant. No topographic changes were found using Galilei.

Purpose: To describe the technique and initial results of laser-assisted dacryocystorhinostomy performed through the canaliculi., Methods: Ten patients with nasolacrimal duct obstruction underwent transcanalicular laser-assisted dacryocystorhinostomy. A silicone tube was inserted through the canaliculi and the ostium into the nasal cavity where it will be kept for 6 months., Results: All ten operations were performed without negative occurrences. One patient presented displacement of the silicone tube one day after surgery. Nine of the ten patients reported disappearance of epiphora at the end of the first week following surgery. During the first month, one of these patients presented with epiphora due to obstruction of the lacrimal-nasal fistula and another lost the silicone tube in the first month following surgery., Conclusions: Transcanalicular laser-assisted dacryocystorhinostomy is a potentially useful method to perform dacryocystorhinostomy.
