Purpose
To evaluate the accuracy of intraocular lens biometry and therefore the refractive outcome after combined phacovitrectomy in patients with primary rhegmatogenous retinal detachment (RD).
Methods
This prospective study included 59 patients (24 women and 35 men) with the diagnosis of primary retinal detachment who underwent primary phacovitrectomy in 2012 with an additional gas tamponade. Preoperative intraocular lens biometry was performed using the IOL-Master (Carl Zeiss Meditec AG). Exclusion criteria were the following: follow up less than 6 months, multimorbid patients, pseudophakia, previous surgery and silicone oil tamponade. Main outcome measure was the IOL power prediction error (PE). Cofactor analysis included patient demographics, macula status and best corrected visual acuity (BCVA, logarithm of the minimum angle of resolution, log MAR).
Results
Fifty-nine patients (mean age 59, 24 women and 35 men) were enrolled. Thirty-three patients presented with a “macula-on” retinal detachment (57%), whereas 26 patients had a “macula-off” retinal detachment (43%). At the 6 months follow-up, the mean IOL power PE for all 59 patients was -0.07 diopters +/- 0.91 SD. “Macula-on” patients showed a mean IOL power PE error of -0.15 diopters +/- 0.53 SD and “macula-off” patients 0.04 diopters +/- 1.23 SD. Mean BCVA significantly improved from 0.84 log MAR +/- 0,62 SD at baseline to 0.27 log MAR +/- 0.32 SD at the 6 months follow-up.
Conclusions
Phacovitrectomy is a safe and effective procedure with a good refractive outcome for the treatment of patients with retinal detachment. Our results suggest that the IOL power PE does not depend on the macula status.
