Joia, MD, Jonas M. Dürmüller, MD, Willi Halfter, PhD, Carsten H. Meyer, MD, PhD,  \nPaul Bernhard Henrich, MD, PhD  \nPurpose: To compare the capsulotomy rim morphology of anterior lens capsules obtained by 5 femtosecond laser–assisted cataract surgery (FLACS) platforms: Catalys, FEMTO LDV Z8, LensAR, LenSx, and Victus.  \nSetting: University of Basel, Basel, Switzerland.  \nDesign: Experimental study.  \nMethods: Anterior lens capsules from 6 interventions per laser platform were collected (N = 30) . 4 of each were assessed under light microscopy (LM; n = 20), and 2 were assessed under scanning electron microscopy (n = 10) . A qualitative evaluation of all samples was conducted, as well as a semiquantitative analysis of the extent of irregularities present in LM samples. The Dunn multiple comparisons test was conducted to determine which lasers produced significantly smoother capsulotomies.  \nResults: Irregularities along the lens capsule rim were observed in all samples. Distinct irregularities were observed for Catalys  \n(unconnected laser pulses bordering the capsulotomy), FEMTOLDV Z8 (numerous additional rows of laser pulses), and LensAR (at least one section with multiple rows of laser pulses) . Victus demonstrated a significantly higher degree of smoothness of capsulotomy (median = 306 degrees) compared with Catalys (median = 171 degrees) (P = .02) . The medians for other laser platforms fell between these values.  \nConclusions: Different laser platforms produce morphologically and quantitatively distinct irregularities, which may influence capsulotomy strength differently. FEMTO LDV Z8, a lowenergy laser, did not produce a smoother capsulotomy than the high-energy lasers . Our results suggest that, with current technologies, the precision of the laser is more important than the pulse energy in determining the regularity of the capsulotomy surface .  \nJ Cataract Refract Surg 2026; 52:74–80 Copyright © 2025 The Author(s).

On a macroscopic level, FLACS capsulotomies are positioned more accurately and are rounder in shape compared with  \nCPCS capsulotomies, leading to a better centration of the intraocular lens in the capsular bag (compare Figure 1, A and C) .5–8 However, on a microscopic level, FLACS capsulotomy rims are irregular, characterized by tags, aberrant laser pulses, indentations, and notches.9,10 By contrast, CPCS capsulotomy rims are smooth and homogeneous (compare Figure 1, B and D) .11  \nThe microscopic irregularities seen in FLACS capsulotomies may influence surgical outcomes. For instance, discontinuous laser pulses could result in an incomplete separation of the created flap from the anterior lens capsule.12 In addition, the irregularities lead to an uneven stress distribution along the capsulotomy’s circumference with focal points of high mechanical stress, which weaken the  \nSubmitted: April 3, 2025 | Final revision submitted: August 3, 2025 | Accepted: August 4, 2025  \nFrom the University of Basel, Basel, Switzerland (Joia); Universita` della Svizzera Italiana, Lugano, Switzerland (Dürmüller, Henrich); Department of Ophthalmology, University of Basel, Basel, Switzerland","cbCaibv0t0CEnxoY","https://ap.wps.com/l/cbCaibv0t0CEnxoY","pdf",1058212,"English","# Purpose\n# Methods\n## Sample collection and imaging\n## Irregularity assessment\n# Results\n# Conclusions","[{\"question\":\"What was the purpose of this study?\",\"answer\":\"The study compared capsulotomy rim morphology produced by five FLACS platforms.\"},{\"question\":\"How were the lens capsules evaluated?\",\"answer\":\"Anterior lens capsules from each platform were assessed using light microscopy and scanning electron microscopy, with qualitative review and semiquantitative analysis of irregularities.\"},{\"question\":\"Which laser platform produced the smoothest capsulotomy edges?\",\"answer\":\"Victus demonstrated significantly higher smoothness compared with Catalys, while other platforms had median values between these extremes.\"}]","Capsulotomy Morphology in Cataract Surgery - Comparison of Five Femtosecond Lasers | PDF",1790744761,18]
