Comparison of accuracy and axial length acquisition success rate by three types of swept-source OCT-based biometers.

Purpose: To compare three biometers equipped with swept-source optical coherence tomography (OCT), including ARGOS (OCTB1), IOLMaster 700 (OCTB2), and Anterion (AS-OCTB). The primary aim was to assess the axial length (AL) acquisition success rates, and secondary aims included comparing parameters obtained from the three devices and evaluating postoperative refractive prediction errors.

Setting: Chukyo Eye Clinic, Nagoya, Japan.

Accuracy of recent intraocular lens power calculation methods in post-myopic LASIK eyes.

This retrospective study compared postoperative prediction errors of recent formulas using standard- or total keratometry (K or TK) for intraocular lens (IOL) power calculation in post-myopic LASIK patients. It included 56 eyes of 56 patients who underwent uncomplicated cataract surgery, with at least 1-month follow-up at Keio University Hospital in Tokyo or Hayashi Eye Hospital in Yokohama, Japan. Prediction errors, absolute errors, and percentage of eyes with prediction errors within ± 0.

Near Add Power of Glaucoma Patients with Early Presbyopia.

Glaucoma medication may accelerate the progression of presbyopia. The aim of this study was to compare presbyopia between controls and patients with glaucoma in their 40s. This was a cross-sectional study of bilateral phakic participants aged between 40 and 49, which included controls ( = 114, mean age 46.

Presbyopia, Dry Eye, and Retinal Thickness in the Middle-Aged Population: Focusing on Sex Differences.

Purpose: Risk factors for presbyopia have not been fully determined although previous studies suggested presbyopia was associate with age, dry eye, and retinal ganglion cell complex thickness (GCC). We accessed these signs and common ocular symptoms in the middle-aged population focusing on sex differences when women have drastic hormonal change.

Methods: This cohort study consecutively enrolled 2743 patients aged 36-45 years (n=1000), 46-55 years (n=1000), and 56-65 years (n=743).

Establishing the cutoff value of near visual acuity for assessment of early presbyopia.

Purpose: There is limited evidence to evaluate the numerical cutoff point for detecting early presbyopia. Thus, we aimed to establish a clinically relevant optimal cutoff value of near visual acuity for detecting early presbyopia.

Study Design: Prospective diagnostic accuracy study.
