Prognostic Factors for Low Visual Acuity after Cataract Surgery with Vitreous Loss

Area of Science:

• Ophthalmology
• Surgical Outcomes
• Vision Science

Background:

• Cataract surgery is a common procedure, but complications like vitreous loss can impact visual outcomes.
• Understanding factors influencing visual acuity after vitreous loss is crucial for patient management.

Purpose of the Study:

• To identify prognostic factors associated with low visual acuity in patients experiencing vitreous loss during cataract surgery.

Main Methods:

• Retrospective case study of 179 patients with vitreous loss during cataract surgery.
• Data included demographics, visual acuity, ocular comorbidities, and intraocular lens (IOL) details.
• Low visual outcome defined as best corrected visual acuity (BCVA) < 20/40.

Main Results:

• Low visual outcome was independently associated with persisting postoperative complications (OR 6.25), preexisting ocular comorbidities (OR 4.45), and secondary IOL implantation (OR 10.36).
• Factors like pars plana vitrectomy, age > 70, gender, axial length, surgeon experience, corneal suturing, and anterior chamber IOL implantation were not significantly associated with poor outcomes.
• Mean follow-up was 12 months.

Conclusions:

• Ocular comorbidities, secondary IOL implantation, cystoid macular edema, and additional surgical complications are linked to low visual outcomes after cataract surgery with vitreous loss.
• Identifying these risk factors can help in surgical planning and patient counseling.
