AI Article Synopsis
- The study aimed to analyze how vitreous presentation (VP) during extracapsular cataract surgery affects patients' vision one year after surgery.
- A total of 230 VP patients were compared to a random sample of 521 nonvitreous presentation (NVP) patients, with visual outcomes assessed by a certified examiner.
- Results showed no significant difference in the percentage of patients achieving good vision (20/40 or better) between VP and NVP, but VP patients experienced worse overall outcomes, including more complications and lower satisfaction ratings.
Article Abstract
Purpose: The purpose of this study was to determine the effects that vitreous presentation (VP) during extracapsular cataract surgery has on patients' 1-year postoperative vision.
Design: The study was a prospective, long-term, clinical trial.
Methods: The study took place at 19 Department of Veterans Affairs medical centers. Patients having VP during cataract surgery and receiving a posterior chamber (PC) intraocular lens (IOL) (230 patients) were prospectively compared with a 5% random sample of nonvitreous presentation (NVP) cataract surgery patients (521 patients). Best-corrected visual acuity (BCVA) at 1 year was obtained by a masked, certified examiner.
Results: There was no statistical difference (P = .089) between the VP patients receiving PC IOL and the NVP patients in percentage of patients having BCVA of 20/40 or better at 1 year (91.1% vs 94.9%). There were significantly more PC IOL VP patients than NVP patients with BCVA of 20/50 or worse at some time during the first postoperative year (21.6% vs 10.9%; P = .0003), significantly fewer with BCVA of 20/20 or better at 1 year (27.8% vs 38.8%; P = .013), and significantly more with cystoid macular edema (11.5% vs 3.6%; P = .0002), retinal detachment (4.3% vs 0.2%; P = .0002), and uveitis (3.4% vs 0.6%; P = .012). The NVP patients rated their vision as very good or excellent significantly more often than the VP patients (71% vs 58%; P = .025).
Conclusions: Vitreous presentation during extracapsular cataract surgery leads to somewhat worse overall outcomes in patients, although the majority of patients with VP do reasonably well.

Objective: Ciliary body medulloepithelioma (CBME), a pediatric intraocular tumor with potential for locally aggressive behavior and metastasis, may present with a diverse spectrum of clinical and histopathologic features leading to diagnostic and management challenges. Examination of unusual CBME cases highlights challenges and modern diagnostic techniques which facilitate accurate diagnosis and guide management.
Methods: A retrospective clinicopathologic analysis of 6 patients with unusual clinical or pathologic features of CBME was performed.

Purpose: To evaluate visual outcomes and quality of vision following bilateral implantation of a hydrophobic acrylic intraocular lens (IOL) in eyes targeted for emmetropia.
Methods: This was a prospective, single arm study. Subjects were bilaterally implanted with the Clareon PanOptix IOL and evaluated at 1 and 3 months postoperatively.
Five cases of transient anterior subcapsular vacuolar lens opacities following trabeculectomy using a dispersive ophthalmic viscosurgical device (OVD) performed by the same surgeon were reviewed at Shimane University Hospital from February to June 2024. All cases presented with anterior vacuolar subcapsular lens opacities observed seven days after surgery, which gradually resolved without specific interventions. Detailed surgical records and clinical outcomes were collected, and the findings suggest that these opacities, characterized by their transient and vacuolar appearance, should be recognized as an early complication of trabeculectomy, potentially linked to the use of dispersive OVDs.

Purpose: This study aimed to evaluate the accuracy and quality of healing of main corneal incisions in femtosecond laser procedures in cataract surgery.
Methods: It was a prospective, non-randomized, investigator-masked study. A total of 37 eyes of 37 patients with indication for cataract surgery were separated into two groups in this prospective, nonrandomized study: Femto group, with incisions automated by femtosecond laser (18 eyes), and Phaco group, with incisions made using a keratome (19 eyes).
