Abstract Details


To determine the safety of the Soft Lens Assisted Contact Interface (Laser SoftFit TM) patient interface and compare its intraoperative results to the contact interface of the LenSx ® femtosecond laser (FSL) platform.


Kaşkaloğlu Eye Hospital, İzmir, Turkey


Fifty eyes underwent femtosecond laser assisted cataract surgery (FLACS) using LenSx ® laser platform (Group 1), using the conventional contact technique. FLACS was performed in another 50 eyes, using Laser SoftFit TM patient interface of LenSx ® FSL platform (Group 2). The groups were compared in terms of intraoperative complications (corneal folds) and surgical results (incomplete and free capsulotomies, incomplete phacofragmentation and unopened incisions).


Both groups shared similar demographics (age; p=0.13) and eye properties (p-values for visual acuity, axial length, mean keratometry, IOL power and type of intraocular lens preferred; 0.57, 0.6, 0.51, 0.09 and 0.343, respectively). Corneal folds decreased from 42% to 6% after the use of Laser SoftFit TM patient interface (p=0.0001). Incomplete capsulotomies were less common (none versus 12%, p=0.027) and free floating capsulotomies were more frequent (92% vs 18%, p=0.0001) with the use of Laser SoftFitTM patient interface. Incomplete phacofragmentation and unopened incisions were seen at a similar rate in both groups (p=0.436 and 0.204, respectively).


The use of Laser SoftFit TM patient interface decreased the incidence of corneal folds and resulted in better capsulotomy outcomes during FLACS. The impact of Laser SoftFit TM patient interface on completeness of lens fragmentation and corneal incisions was not significant.
