This report extends a previous paper on the various characteristics of the most popular phacoemulsification devices. An evaluation of 11 devices by ten different manufacturers was attempted. Only five manufacturers of six devices agreed to critical evaluation or reevaluation. As in the previous report, the devices were compared for level of patient safety, dependability, efficiency, ease of usage, and operating cost for the first 1,000 cases. At the completion of this study, we ranked the nine devices evaluated over the past 17 months as follows: (1) United Surgical (Optikon) Systems Plus, (2) Optical Micro Systems (OMS), (3) United Surgical (Optikon) Phacotron, (4) CooperVision 10,000, (5) Site XTR, (6) CooperVision KCP, (7) CooperVision 9001, (8) Phakosystems CES 4000 and (9) United Sonics. To enhance the usefulness of this consumer's guide, we asked 40 experienced cataract surgeons what they wanted in the "ideal" phacoemulsification device. The opinions of 27 who responded are included.

The impact of speculum uses on the incidence of blepharoptosis in patients undergoing phacoemulsification surgery: A prospective analysis.
Indian J Ophthalmol
February 2025
Orbit and Oculoplasty, Aravind Eye Hospital, Thavalakuppam, Pondicherry, India.
Purpose: The primary objective of this study was to investigate the possible role and assess the potential relationship of speculum use during phacoemulsification surgery in the occurrence of blepharoptosis.
Methods: Our study is a prospective observational design to analyze patients who underwent phacoemulsification surgery under topical anesthesia between October 2017 and May 2018 at a tertiary eye hospital in South India. All patients had their Margin Reflex Distance 1 (MRD1), levator palpebrae superioris (LPS) function, and lid crease distance (LCD) measured before and after surgery on day one, one month, three months, and six months to evaluate the extent of ptosis at each time point that was recorded clinically and photographic documentation for accurate evaluation.
Comparative evaluation of several toric intraocular lens calculators for predicting postoperative refractive astigmatism in cataract surgery: a real-world study.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Peking University Third Hospital, 49 North Garden Rd., Haidian District, Beijing, China.
Background: This study aims to comprehensively evaluate the predictive accuracy of six widely used toric intraocular lens (IOL) calculators in eyes undergoing cataract surgery with toric IOL implantation.
Methods: This retrospective study reviewed 53 eyes of 53 patients that underwent cataract extraction with toric IOL implantation using Zeiss 709 M. Six toric IOL calculators were evaluated: Barrett toric calculator (with predicted PCA, measured PCA, and TK), Kane formula (predicted PCA), and EVO 2.
Comparison of Ultrasound Energy Delivered to the Anterior Segment Across Different Phacoemulsification Surgical Platforms.
Med Devices (Auckl)
January 2025
Department of Ophthalmology and Visual Sciences, John A Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.
Purpose: The aim of this study was to use calorimetry to understand the difference in energy transferred by three phacoemulsification surgical platforms to the eye.
Patients And Methods: A phacoemulsification tip was lowered into a double-walled calorimeter filled with distilled water. The foot pedal was depressed for 30 seconds and the change in temperature of the water was measured by a temperature probe.
Third-Generation Trabecular Micro-Bypass Implantation with Phacoemulsification for Glaucoma.
Ophthalmol Ther
January 2025
Rocky Vista University, Englewood, CO, USA.
Introduction: This retrospective, consecutive, real-world case series assessed the efficacy and safety of third-generation trabecular micro-bypass stent implantation (iStent infinite) with phacoemulsification in patients with mild-to-moderate primary open-angle glaucoma (POAG).
Methods: Patients underwent phacoemulsification combined with implantation of iStent infinite (containing three stents) by a single U.S.
Impact of central corneal astigmatism on postoperative visual outcomes in patients undergoing trifocal intraocular lens implantation.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Eye & ENT Hospital, Fudan University, 83 Fenyang Road, Xuhui District, Shanghai, 200031, China.
Background: To investigate the impact of central corneal astigmatism on postoperative visual outcomes in patients with trifocal intraocular lens (IOL) implantation.
Methods: This retrospective study included 278 eyes of 278 patients who underwent uneventful cataract surgery with implantation of the trifocal IOL (AT LISA tri 839MP). Patients were divided into two groups according to the total corneal refractive power (TCRP) in 3 mm zone centered on the corneal apex: low astigmatism group, TCRP ≤ 0.
