Comparison of early changes in ocular surface markers and tear inflammatory mediators after femtosecond lenticule extraction and FS-LASIK.

Aim: To compare the short-term impacts of femtosecond lenticule extraction (FLEx) and femtosecond laser-assisted laser keratomileusis (FS-LASIK) on ocular surface measures and tear inflammatory mediators.

Methods: This prospective comparative nonrandomized clinical study comprised 75 eyes (75 patients). Totally 20 male and 15 female patients (age 21.

Vitreoretinal surgeons' experience and time interval from pars-plana vitrectomy to cataract extraction.

Aim: To identify the association of the vitreoretinal surgeons' experience with the time interval between pars-plana vitrectomy (PPV) and cataract extraction (CE).

Methods: Eyes with prior PPV and following CE were included in this retrospective cohort study. The years of practice and the annual case volume were used to describe the surgeons' experience.

Accuracy of eight intraocular lens power calculation formulas for segmented multifocal intraocular lens.

Aim: To evaluate the accuracy of eight different intraocular lens (IOL) power calculation formulas for a segmented multifocal IOL.

Methods: A total of 53 eyes of 41 adult cataract patients who underwent phacoemulsification and implantation with the SBL-3 segmented multifocal IOL between January 1, 2017 and January 31, 2019 were included in this retrospective study. Preoperative biometry measurements were obtained using an IOL Master.
