27-gauge sutureless vitrectomy under topical anesthesia: A pilot study.

BACKGROUND

The implementation of the 27-gauge (G) sutureless vitrectomy technique is associated with a marked shortening of surgery time, faster healing of scleral and conjunctival wounds, less severe conjunctival scarring, limited postoperative corneal astigmatism, and marked improvement in the postoperative comfort of patients. The traditional methods of anesthesia for vitrectomy surgery are quite varied and each has its own potential for complications.

OBJECTIVES

To assess the feasibility and safety of 27G pars plana vitrectomy (PPV) performed under local topical anesthesia for diabetic maculopathy, asteroid hyalosis and vitreomacular traction syndrome associated with high myopia.

MATERIAL AND

METHODS

Three carefully selected patients with various vitreoretinal disorders underwent primary 27G PPV performed by a single surgeon under local topical anesthesia. Patients were analyzed in regard to best corrected visual acuity, intraocular pressure, intraoperative/postoperative complications, intraoperative/postoperative pain, and surgery time.

RESULTS

All patients showed postoperative improvement in visual acuity. No decrease in intraocular pressure below 10 mm Hg was documented on postoperative day 1. Furthermore, no postoperative complications were recorded during the six-month follow-up, and evident improvement in the anatomical status was confirmed using ophthalmic coherence tomography in all cases.

CONCLUSION

Our findings support that 27G PPV performed solely under local topical anesthesia is safe and effective for treating selected vitreoretinal disorders.
