Purpose: We investigated the effect of the time of secondary intraocular lens (IOL) implantation on final visual acuity and other causes affecting visual prognosis in cases left aphakic after open globe injury.
Methods: The study included 62 eyes of 62 patients left aphakic after the repair of open globe injury between 2012 and 2019. Demographic characteristics, trauma zone, ocular trauma score, type of injury, time of secondary IOL implantation, final best-corrected visual acuity (BCVA), and complications were recorded for each patient.
Results: The mean follow-up time of 62 patients was 25.05 ± 12.59 months. The preoperative BCVA was found to be 2.40 ± 0.86 logarithm of the minimum angle of resolution (logMAR), while the postoperative final BCVA was found to be 0.53 ± 0.70 logMAR (p < 0.01). The mean interval timing of secondary sulcus foldable IOL implantation was determined to be 3.79 ± 4.04 months. No correlation was observed between secondary IOL implantation time and final BCVA (r = 0.140, p = 0.319). Furthermore, when only pediatric patients were taken, an excellent positive correlation was found between the secondary IOL implantation time and final BCVA logMAR (r = 0.895, p < 0.01). Multiple linear regression on final BCVA with age, revealed a significant model explaining 48.0% of the variability with younger age and better final BCVA with as significant coefficients (p = 0.007).
Conclusions: Although time interval between primary repair and secondary IOL implantation to correct aphakia does not effect final BCVA in adult patients, earlier surgery should be considered for amblyopia management in pediatric patients.

Purpose: To identify the minimally required number of distances of visual acuity (VA) measurements for the reliable estimation of the visual acuity curve (VAC) and area of the curve (AoC) in presbyopia correction.
Patients And Methods: The study was divided into a validation and a clinical phase with a total recruitment of 120 participants (120 eyes) who underwent uncomplicated pseudophakic presbyopia surgery with bilateral premium intraocular lenses (IOL) implantation. This study was conducted in the Department of Ophthalmology, University Hospital of Alexandroupolis, Alexandroupolis, Greece.

Purpose: The research investigates the efficacy of hydroxypropyl methylcellulose (HPMC) treatment in facilitating the development of compact water droplets on the rear surface of synthetic lenses with capsule imperfections during the process of fluid-air exchange.
Method: This study examined four patients with intraocular lens (IOL) implants and posterior capsule defects who experienced the formation of dense water droplets on the posterior surface following fluid-air exchange. When this occurrence obstructs fundus visualization during surgery, it is recommended to suspend the surgical procedure.
Purpose: To observe and explore the correlation between visual outcomes and intraocular lens (IOL) stability after tri-focal IOL implantation in eyes with high myopia.
Methods: Patients with highly myopic cataract (axial length > 26 mm) were enrolled in this prospective study. Thirty-one eyes (31 patients) received implantation of a trifocal IOL (AcrySof IQ PanOptix TFNT00).
Purpose: To evaluate residual refractive errors after intraocular lens (IOL) extraction and the safety and effectiveness of refractive correction procedures.
Methods: The eligibility criteria for this systematic review were patients who had undergone cataract or clear lens extraction and had experienced residual refractive error. All study designs were considered for inclusion and non-English publications, non-peer reviewed articles, books, and systematic reviews were excluded.

Purpose: To apply a new method, the Taylor Diagram, and a new concept, the centered root mean square error (cRMSE), in evaluating the performance of IOL formulas.
Methods: The preoperative biometrics were measured with the IOLMaster 700 (Carl Zeiss Meditec) and the postoperative spherical equivalent refraction (SER) was calculated in 888 anonymous patients. The Taylor Diagram was applied to visualize the centered root mean square error (cRMSE) and the correlation coefficient between the predictions and the observations (R).
