Results

Intermediate visual acuity was better in the DIB group (p<0.01 in both eyes and p<0.01 in one eye), and near visual acuity was also better in the DIB group (p=0.01 in both eyes). (p=0.018 in both eyes, p<0.01 in one eye). Patient satisfaction was significantly better for DCB at intermediate distances (p=0.045), but there were no significant differences in either spectacle dependence or dysphotopsia.

Baseline Characteristics

The subjects were patients who underwent lens reconstruction in both eyes at the Department of Ophthalmology, Japanese Red Cross Wakayama Medical Center from October 2021 to April 2022.

Participant flow

The study subjects were patients aged 20 years or older who underwent lens reconstruction surgery at our hospital between October 2021 and April 2022. After the physician in charge explained the study to the patients, written consent was obtained. Exclusion criteria were macular disease, glaucoma including central visual field abnormality, previous internal ophthalmic surgery, apparent strabismus in the distance or near on the Cover-Uncover Test that would make binocular unification difficult after surgery, astigmatism with a cylinder power of -2.00 D or greater, and expected postoperative refraction value of -2.00 D or greater.

Adverse events

none

Outcome measures

The primary endpoints were one- and binocular naked eye visual acuity at distance (5 m) and intermediate (70 cm) and one- and binocular visual acuity at distance, intermediate, and near (30 cm) under full correction of distance vision at 3 months postoperatively.
First, after measuring the other-sensory refraction values using TONOREF2 (NIDEK), the distance naked eye visual acuity and intermediate visual acuity were measured. Then, using the lens exchange method with reference to the other refraction values, the distance fully corrected visual acuity was measured, and the obtained refraction values were used to measure intermediate and near visual acuity.

The reason for starting the entry one and a half month in advance is that we currently perform the surgery about two weeks after the application for the cataract surgery, so we expect to be able to enter the target number of subjects before and after the lens change. It is expected that the target number of patients will be able to enter before and after the lens change. The subjects will be fully explained about this study both orally and in a written explanation, and written consent will be obtained. For patients whose consent has been obtained, the medical record will be used to obtain information on the patient's age, gender, intraocular lenses used, preoperative and intraoperative complications, and visual acuity and refraction before and after surgery (3 months+-2 weeks after surgery). In addition, we will conduct a questionnaire survey on the wearing of glasses before and after surgery and postoperative subjective symptoms.
