Purpose

To evaluate long term results following vitrectomy for dropped nucleus associated with Posterior capsule rupture in cataract surgery including visual acuity and long term complications

Setting

District General Hospital in the public sector serving a population of approximately 400,000. The unit receives referrals from an neighboring hospital that does not have Vitreoretinal (VR) facilities and also from other hospitals when there is no VR surgeon available.

Methods

Patients who underwent the procedure were identified using Medisight records over a 6 year period starting from April 2020. Individual records were then reviewed and the data collected included Preoperative visual acuity (PreVA) (before cataract surgery),final visual acuity (FinVA) (at discharge or last visual acuity recorded if the patient attended for any other reason in the eye clinic). Prexisting pathology was noted as well as any complications. The timings of the vitreoretinal intervention following the initial cataract surgery was also collected.

Results

A total of 23 records were reviewed. Two patients were excluded as post operative data was not available. The mean age was 74.8 and 10 of the patients were male. The mean PreVA was 0.56. and the mean FinVA was 0.32 (range 0.0- 1.3). One patient with a history of previous retinal detachment surgery had a significant subchoroidal haemorrhage involving the macula at cataract surgery and the Final VA was 1.3. One patient had progression of a preexisting mild epiretinal membrane and achieved a final VA of 1.00. The mean FinVA was 0.22 if these 2 outliers were excluded

61.9 % (13/21) of patients had preoperative documentation suggesting advanced cataract (white/ brunescent).

Cystoid Macular oedema (CMO) at 4-6 weeks post vitrectomy- 71.4%15/21) had CMO and 2/21 had no CMO. Documentation relating to CMO (or lack of) at the 4-6 week period was missing in the 4/21. One patient developed chronic CMO which was ongoing 4 years after vitrectomy.

The mean time to vitrectomy from cataract surgery was 15.71 days (range 16-29). All patient who had vitrectomy more than 2 weeks following initial cataract surgery were due to late referral from external units. No complications that could directly be related to the vitrectomy were identified in this cohort

Conclusion

The outcomes measured in terms of final VA was good in this cohort. The timing to intervention did not appear to have any impact on the outcome. CMO was seen frequently at the 4-6 week period. The sample size was too small to draw any conclusions regarding timing of vitrectomy and CMO but could be a focus for further study.
