    Vitreous loss during cataract surgery occurred in 10.7% of eyes. While most eyes with vitreous loss achieved comparable vision, significantly fewer reached very good visual acuity compared to fellow eyes.

    Area of Science:

    • Ophthalmology
    • Surgical Outcomes
    • Visual Acuity

    Background:

    • Cataract surgery is a common procedure.
    • Vitreous loss is a potential complication during cataract surgery.
    • Understanding the impact of vitreous loss on visual outcomes is crucial.

    Purpose of the Study:

    • To determine the incidence of vitreous loss during bilateral cataract surgery.
    • To compare postoperative visual acuity in eyes with and without vitreous loss.
    • To analyze the effect of unilateral vitreous loss on visual outcomes compared to fellow eyes.

    Main Methods:

    • Retrospective analysis of 448 patients (896 eyes) undergoing bilateral cataract surgery.
    • Categorization of eyes based on the presence or absence of vitreous loss.

  • Comparative analysis of visual acuity outcomes between eyes with and without vitreous loss, and between fellow eyes in unilateral cases.

    • Main Results:

    • Vitreous loss occurred in 10.7% of eyes (96 out of 896).
    • Eyes with vitreous loss had a lower percentage of achieving very good visual acuity postoperatively compared to eyes without vitreous loss.
    • In unilateral vitreous loss cases, 12% had poorer vision than their fellow eye, and significantly fewer achieved very good visual acuity (8.7-11.1%) compared to fellow eyes (21.5-22.2%).
    • Combined vitreous loss with accidental extracapsular cataract extraction worsened visual performance.

    Conclusions:

    • Vitreous loss is associated with a reduced likelihood of achieving excellent visual outcomes after cataract surgery.
    • While most eyes with vitreous loss achieve functional vision, a notable proportion experience poorer outcomes compared to their fellow eye.
    • The findings underscore the importance of meticulous surgical technique to minimize vitreous loss and optimize patient visual recovery.
