Clinical outcomes of a beveled tip, ultra-high speed, 25-gauge pars plana vitrectomy system.

ABSTRACT:

Objective

To report the clinical outcomes of a 25-gauge, beveled-tip, 10,000 cuts-per-minute (cpm) microincisional vitrectomy surgery (MIVS) system.

Methods

Prospective case series of eyes undergoing primary pars plana vitrectomy (PPV) for common vitreoretinal indications. Main outcome measures were: rate of achieving surgical objectives, operative times, number of surgical steps, use of ancillary instruments, corrected distance visual acuity (CDVA), and adverse events (AE).

Results

The surgical objectives were achieved in all eyes. Mean total operative time (TOT), core, shave and total vitrectomy times were 1891 ± 890, 204 ± 120, 330 ± 320, 534 ± 389 s, respectively. Mean number of surgical steps was 4.3 ± 1.5. Mean number of ancillary instruments used was 4.5 ± 1.9. Mean CDVA improved by 0.53 ± 0.56 logMAR units (P < 0.001) 3 months postoperatively. AE included elevated IOP (8%), hypotony (6%), and re-detachment (2%). Majority (82%) had no postoperative discomfort. The number of surgical steps demonstrated a positive correlation with TOT (p < 0.05), number of ancillary instruments used (p < 0.05), and postoperative Day 1 IOP (p < 0.05). The number of times ancillary instrumentation was used demonstrated a positive correlation with TOT (p < 0.05).

Conclusion

Beveled-tip, 10,000 cpm MIVS system effectively and safely performs common VR procedures of varying complexity and may reduce operative times and use of ancillary instrumentation.

Project description:PurposeAn increasing number of posterior segment disorders is routinely managed with pars plana vitrectomy (PPV). In older, phakic patients cataract formation is expected within the first two years after surgery. For younger patients its progression is individually fluctuating. This study uses an objective quantitative measurement for lens-status-monitoring after PPV with silicone oil to derive predictions for progression and severity of post-operative lens opacification evaluated in patients with rhegmatogenous retinal detachment (RRD).MethodsData acquisition was performed prospectively between March 2018 and March 2021. PentacamHR® Nucleus Staging mode (PNS) was used to objectively gather data about nuclear cataracts after PPV at different time points. Data was grouped into training and test sets for a mathematical prediction model. Via backward variable selection method a mathematical formula was set up by means of which predictions about lens densitometry (LD) can be calculated.Results20 males [58.8%] and 14 females [41.2%] matched the inclusion criteria (mean age 50.6 years [23-75; ±12.3]). Average follow-up was 8.1 months (3,4-17.4; ±3.4). Mean baseline LD of the treated and fellow eye before surgery was 11.1% (7.7%-17.6%; ±2.0) and 11.2% (7.7%-14.8%; ±1.5), respectively. Predicted LD values by the model for five pre-selected patients closely match the observed data with an average deviation of 1.06%.ConclusionsUsing an objective parameter like LD delivered by the PentacamHR® PNS mode additionally to the patient's age allows us to make an individual prediction for any time after PPV with silicone oil due to RRD for all ages. The accuracy of the model was stronger influenced by baseline LD as cofactor in the equation than patient's age. The application for the prediction lens opacification [which can be accessed for free under the following link (https://statisticarium.com/apps/sample-apps/LensDensityOil/)] can help vitreoretinal surgeons for patient consultation on the possibility to combine PPV with cataract surgery.
