Correlation of angle kappa and angle alpha on visual outcomes in eyes implanted with three types of multifocal intraocular lenses.

To evaluate the correlation between preoperative, postoperative, and change in angle kappa and alpha to visual outcomes following implantation of three multifocal intraocular lenses. This is a retrospective study which included 122 eyes of 61 patients. There were 38 eyes in the Synergy (Johnson & Johnson, USA) group and 42 eyes each from both the Panoptix (Alcon Laboratories, USA) and FineVision (Physiol BVI, Belgium) groups.

Comparison of measurements and calculated lens power using three biometers: a Scheimpflug tomographer with partial coherence interferometry and two swept source optical coherence tomographers.

Purpose: To compare the biometric measurements obtained from the Pentacam AXL Wave, IOLMaster 700, and ANTERION and calculate the recommended intraocular lens power using the Barrett Formulae.

Methods: This was a retrospective cross-sectional study of patients who underwent biometry using the Pentacam AXL Wave, IOLMaster 700, and ANTERION. Flat keratometry (K1), steep keratometry (K2), anterior chamber depth (ACD), and axial length (AL) from each device were measured and compared.

Comparison of white-to-white measurements using four devices and their determination of ICL sizing.

Background: To compare the measurements obtained from the Orbscan II, IOLMaster 700, Pentacam AXL, and Castroviejo caliper and their effects on calculating the recommended implantable collamer lens (ICL) size and postoperative vault measurements.

Methods: This is a retrospective cross-sectional study of patients who underwent ICL surgery by a single surgeon from March 1, 2018 to July 31, 2021. Records were reviewed for the anterior chamber depth (ACD) and white-to-white (WTW) measurements obtained from the Orbscan II, IOLMaster 700, Pentacam AXL, and Castroviejo caliper (WTW only).

Efficacy of an aspheric treatment algorithm in decreasing induced spherical aberration after laser in situ keratomileusis.

Purpose: To determine the effectiveness of an aspheric laser in situ keratomileusis (LASIK) algorithm for myopia with and without astigmatism in minimizing postoperative induction of spherical aberration.

Setting: Four sites in Asia.

Methods: Patients with -1.
