“…[1][2][3][4] In addition, surgery can be performed through incisions of 1.4 mm, [5][6] or even through a 0.9 mm incision, 1 hence inducing less postsurgery astigmatism than conventional coaxial phacoemulsification (CP). [5][6] It is well recognized that in CP, temporal clear corneal incisions (CCI) induce the least astigmatism. The ophthalmic literature estimates that the magnitude of surgically induced astigmatism (SIA) studied by vector analysis is around 0.44 D and 0.88 D, rising as the size of the incision increases.…”

Purpose A comparison of the topographic astigmatism generated after coaxial phacoemulsification (CP) through temporal 2.8 mm incision and biaxial phacoemulsification (MICS) through superioroblique trapezoidal 1.5-2 mm incisions. Setting Centre for Visual Sciences (Instituto de Ciencias Visuales, INCIVI), Madrid, Spain Methods This prospective randomized clinical study included 94 eyes of 64 patients; 43 eyes were operated on through CP and 51 through MICS. Corneal topography was measured before operation, and subsequently after 1, 3, and 6 months. Additionally, a control group (C) of 55 eyes was created (performing two topographies on them); the change in astigmatism was calculated without having performed any surgical procedure. The astigmatic change in the three groups was measured through arithmetic, polar and vector analysis (Alpins method). Results In the vector analysis, results after the first month following surgery were: mean module of the surgically induced astigmatism (SIA) 0.49 ± 0.38 D in CP and 0.48 ± 0.37 D in MICS, while 0.31 ± 0.27 D in group C. Although no statistically significant differences were detected between the two surgical techniques, differences were noted when comparing group C with each of these techniques (Po0.05). The distribution of the SIA axes showed a slight tendency to be located more frequently at around 901 in CP, and at around 501 in MICS. Conclusions The mean module of SIA was similar in CP and in MICS, although the distribution of the direction of such a vector revealed minor differences.

“…Textbooks primarily discuss various bevel angles and shapes without providing outcome data (12) . Advances in phacoemulsification surgery with different phaco microtips, sleeves, and torsional movement have resulted in a very effective procedure for patients, providing faster visual recovery and earlier return to routine daily activities (13) . Higher US power (cumulative dissipated energy) and longer phaco times have been implicated in endothelial cell loss (14,15) .…”

ClinicalTrials.gov Identifier: NCT02089698 ABSTRACTPurpose: To compare the efficiency of surgical procedures using three phaco tip designs in torsional phacoemulsification using the bevel-down technique. Methods: In this prospective, comparative, masked study, patients were randomly assigned to have torsional coaxial microincision cataract surgery using the mini-flared 45-degree Kelman tip, reversed mini-flared 30-degree Kelman tip, or Sidewinder 30-degree Kelman tip. Clinical measurements included preoperative and 3-month postoperative corrected distance visual acuity (CDVA), endothelial cell counts (ECC), and preoperative and 1-day postoperative central corneal thickness (CCT). Intraoperative measurements included phaco time, torsional time, aspiration time, case time, cumulative dissipated energy (CDE), and balanced salt solution volume (BSS). Results: The study evaluated 150 eyes of 150 patients. Intraoperatively, there was no statistically significant difference in cumulative dissipated energy, case time, torsional time, and aspiration time between the three tip configurations. However, less phaco time was used with the mini-flared 45-degree Kelman tip (p=0.02) than that with the Sidewinder 30-degree Kelman tip or reversed mini-flared 30-degree Kelman tip. The mini-flared 45-degree Kelman tip and the reversed mini-flared 30-degree Kelman tip required significantly less balanced salt solution volume than that required by the Sidewinder 30-degree Kelman tip (p=0.009). There was no statistically significant difference in corrected distance visual acuity and endothelial cell counts between tips 3 months postoperatively (p>0.05). Conclusion: All three tips were effective with no intraoperative complications. When using torsional phacoemulsification through microincisions and the prefractu re technique with the bevel-down technique, the mini-flared 45-degree Kelman tip required a lower mean phaco time than the reversed mini-flared 30-degree Kelman tip and the Sidewinder 30-degree Kelman tip.

INTRODUCTION. The purpose of this paper was to determine surgically-induced changes both in corneal topographic parameters and in endothelial cell loss after coaxial microincision cataract surgery (MICS) through temporal 1.8 mm incision. MATERIALS AND METHODS. Evaluation was performed in forty eyes of thirty patients who underwent cataract surgery. Topographic parameters including corneal astigmatism, surface regularity index (SRI), and surface asymmetry index (SAI) were estimated preoperatively and at one week, four weeks, and eight weeks after surgery. A specular microscope was also used for the measurement of the corneal endothelial density (cells/mm
