Lens and Peripheral Retinal Relationships During Vitrectomy: Comparison of 23-, 25-, and 27-Gauge Vitrectomy and Curved Endolaser Probes

ABSTRACT:

Purpose:

This work aims to compare spatial relationships between the crystalline lens and vitrectomy instruments of different gauges.

Methods:

Eight phakic eyes recovered from deceased donors were used after fixation. Valved trocars (27-gauge, 25-gauge, and 23-gauge) were sequentially placed in the superotemporal quadrant 4 mm posterior to the limbus in each eye. Intraocular relationships of vitrectomy and curved endolaser probes were measured for each gauge.

Results:

There were no significant differences in maneuverability between instruments of different gauges. The mean distance from instrument to lens at the geometric center of the globe was 5.5 mm. Vitrectomy probes of all gauges could access the peripheral retina on both sides of the sclerotomy in the 3 to
