Purpose To compare resected lens capsules created by femtosecond laser system with the conventional manual techniques. Methods A prospective, observational case series of 6 patients who underwent capsulotomies performed by an optical coherence tomography‐guided femtosecond laser compared with 6 patients which capsulotomies created with the conventional manual technique. The resected capsules were evaluated histologically. Electron microscopy was performed to examine their capsule edge. Results Histologically the capsule edges produced by manual were smooth and continuous however performed by femtolaser the capsule edges showed small microgrooves in high magnification. Electronmiocroscopically these microgrooves presented as pointed serrated structure like a lacerated jeans. Conclusion The femtosecond laser produced capsulotomies were clinically more precise in diameter and in size however their capsules showed irregular stripped edges than those created with the conventional manual technique. The microgrooves were produced by the laser pulses. A certain weakness of the laser produced edges is to expect and needs more clinical experiences.
