Evaluation value of subjective visual quality examination on surgical indications of the early cataracts based on objective scatter index values.

ABSTRACT:

Aim

To evaluate the subjective visual functions of early cataracts patients and assess their surgical indications.

Methods

Eyes were separated into a control group (Group A without cataract) and two early cataracts groups (Group B with 2.0 ≤ OSI < 3.0 and Group C with 3.0 ≤ OSI < 4.0). The objective scatter index (OSI), modulation transfer function cut-off frequency (MTF cut-off), and Strehl ratio (SR) values were applied to measure objective visual functions. The contrast sensitivity (CS) and scores of the questionnaires (QOL and VF-14) characterized subjective visual functions. Above visual functions were compared among three groups. Postoperative visual functions in Group B and C were analyzed to assess the outcome of surgery.

Results

Ninety two subjects (126 eyes)
