Purpose: To investigate the possible risk factors for treatment failure in patients who had undergone Preserflo Microshunt (PMS) implantation, using anterior-segment optical coherence tomography (AS-OCT) to analyze the internal structures of the bleb.
Methods: The PMS blebs of 54 patients were evaluated with AS-OCT. A mathematical model was used to calculate the total filtering surface of the episcleral fluid cavity (EFC) and the hydraulic conductivity (HC) of the bleb wall.
Article Synopsis
- A study evaluated the wavefront aberration profile of a phakic intraocular lens (PIOL) with a strength of -4.5 D among four patients who previously underwent myopic laser refractive surgery.
- Pre-surgery data simulated the effects of PIOL implantation, while post-surgery data helped develop a model of the eyes after LASIK surgery.
- The findings showed that the PIOL did not degrade optical quality compared to post-LASIK conditions, and its optical quality improved as pupil size increased.
Purpose: To evaluate the efficacy of astigmatic correction with two types of toric intraocular lenses (IOLs) after femtosecond laser-assisted cataract surgery (FLACS) in eyes with low-to-moderate corneal astigmatism using intraoperative aberrometry for optimizing the position of the toric IOL.
Methods: Retrospective study includes a total of 99 eyes of 73 patients with anterior keratomeric astigmatism ≤ 3 D and undergoing FLACS (Catalys, Johnson & Johnson Vision) with implantation of a monofocal (Ankoris, PhysIOL) or a multifocal toric IOL with the same platform (Pod FT, PhysIOL). In all cases, intraoperative aberrometry was used (Optiwave refractive analysis, ORA, system, Alcon).
Femtosecond laser-assisted capsulotomy for treatment of bilateral anterior capsule contraction.

A 51-year-old woman developed severe fibrosis and occlusion of the visual axis in 1 eye, maintaining a pinhole aperture in the fellow eye, 2 months after uneventful cataract surgery and implantation of a hydrophilic trifocal intraocular lens in the capsular bag. She had not exhibited any risk factor for anterior capsule contraction preoperatively. Femtosecond laser-assisted capsulotomy with a fluid-filled interface system was used to perform a simultaneous anterior capsulotomy in both eyes.

Methods: FLACS was performed on six porcine eyes and a Kamra corneal inlay had been implanted, exploring the lens under the surgical microscope. Another Kamra corneal inlay was attached to the upper part of the transparent hemisphere used for calibration of the femtosecond laser.
