To describe the clinical, biometrical and refractive results in combined phaco-vitrectomy with 23G.


24 patients were included in this retrospective case series study. We recorded demographical and ophthalmological data which included: ophthalmic exploration before and after surgery, ocular biometric data, surgical technique, spherical equivalence before and after surgery and complications.


24 patients were included: 17 macular pucker (65%), 4 macular hole (15%), 2 diabetic retinopathy (7%) and 1 non-diabetic hemovitreous (3%). Follow-up time was 12 months (3 to 24 months). Visual acuity before surgery was 0,2 (LP-0,5) and after surgery was 0,7 (0,3-1,0) with p=0,0001. Median spherical equivalent after surgery was -0,59 (-3 a +1). 5 intra-operative complications (2 posterior capsular rupture, 2 iatrogenic retinal holes and 1 retinal detachment). 7 complications after surgery: 5 posterior capsular opacities, 1 pucker recurrence and 1 irvine gass syndrome. Final median refraction was contrasted with site of intraocular lens implantation, ocular axial length, IOL model, retinal pathology, air or gas utilization or surgical complication and statistical significance (p=0,034) were found between intraocular lens model (C-Flex vs Akreos).

Effectiveness / Safety:

Combined phacoemulsification with pars plana vitrectomy 23G is safe and effective at short and long time with minimal complications. It is important to notice that final refractive results showed myopic shift (-0,59), a wide range refractive prediction(-3 to +1) and a possible factor found in this study was lens model.
