“…11 OSI has been proven to be closely related to the presence of cataracts and can directly and objectively quantify the changes in the lens of cataract patients. 12 OSI value of early cataract eyes is between 1.0 and 2.9, and OSI value of mature cataract eyes is greater than 3. But Other report suggested that the average OSI value for early cataracts was 3.7.…”

Objective Age-related cataract (ARC) is an eye disease characterized by lens opacity. This study analyzed the correlation between 25 hydroxyvitamin D [25 (OH) D] levels and Interleukin 6 (IL-6) levels in aqueous humor from the patients with ARC, as well as between 25 (OH) D levels and lens opacity, and explored the effect of 25 (OH) D on the pathogenesis of ARC. Methods A retrospective analysis was performed, which included the clinical data from 120 ARC patients and 40 healthy individuals. They were divided into three groups based on the objective scattering index (OSI): 40 healthy individuals (control group), 84 patients with the early cataract (EC group), and 36 patients with the mature cataract (MC group). An electrochemical luminescence method was used to detect the levels of 25 (OH) D and IL-6 in aqueous humor, the OSI of the eye was measured using a visual quality analysis system. The correlation between the changes in the above indicators and ARC was analyzed. Results The OSI and IL-6 levels in the control group, EC group, and MC group increased sequentially (all p < .001), while the levels of 25 (OH) D showed an opposite trend (all p < .001). Conclusion The decrease in 25 (OH) D levels is related to the occurrence and development of ARC, and the relationship between 25 (OH) D deficiency and the pathological mechanism of ARC needs further research.

“…Recently, the application of Objective Quality Analysis System II (OQAS II) in guiding surgery for cataract has been widely used (6)(7)(8)(9). OQAS II directly collects the retinal images of point light sources through the double-pass system and analyzes their point spread function (PSF) (10).…”

“…A previous study has concluded that OSI ≥ 3.0 may be an objective threshold for preoperative decision-making for cataract surgery ( 8 , 9 ). According to another research, the OSI equaling to 3.2 was considered as the critical value for surgical treatment ( 7 ).…”

AimTo evaluate the subjective visual functions of early cataracts patients and assess their surgical indications.MethodsEyes 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.ResultsNinety two subjects (126 eyes) were included in the study. All objective visual function in Group B were significantly better than Group C (all P < 0.01), but worse than Group A (all P < 0.01). Except for 1.5 c/d CS, subjective visual function in Group A were significantly better than Group B and C (all P < 0.05), but there was no significant differences between Group B and C. As for eyes that underwent surgery in Group B and C, all visual functions significantly improved after surgery (P < 0.05), except for 1.5 c/d CS in Group C. There were no significant differences among the three groups after surgery.ConclusionThe subjective visual function can be impaired in early cataracts patients with OSI < 3.0, whose objective visual functions were statistically better than patients with OSI ≥ 3.0. These patients can benefit equally from surgery as patients with OSI ≥ 3.0. Subjective visual functions can be used as surgical indications for these patients.
