Abstract Details

Purpose:

A significant myopic shift has been reported after phacovitrectomy in eyes with cataract and retinal detachment, most probably because of the concomitant macular pathology causing error in the biometric calculations. The current study aimed to compare the accuracy of intraocular lens (IOL) power calculations in combined phacovitrectomy for diabetic tractional retinal detachment to cataract surgery alone.

Setting:

Department of Ophthalmology, Marmara University Medical School, Istanbul, Turkey.

Methods:

In this retrospective study, the predicted preoperative refractive aim was compared with the results of postoperative refraction in the combined surgery group (phacovitrectomy with IOL implantation for cataract and diabetic tractional retinal detachment, n=20) and the control group (phacoemulsification for cataract in eyes with flat retina, n=20). Biometric measurements were performed with the optical low-coherence reflectometry (Lenstar LS900, Haag-Streit AG), and the IOL power was calculated with the SRK/T formula. There was no intravitreal tamponade during measurements.

Results:

The mean (± standard deviation) refractive aim was -0.39 ± 0.22 D and -0.22 ± 0.25 D and the mean achieved refraction was -0.43 ± 1.11 D and -0.26 ± 0.56 D in the combined surgery group and in the control group (P=0.88 and P=0.95, respectively). There was no clinically significant difference between the mean postoperative prediction error of two groups (P=0.96).

Conclusions:

In our study, by using the optical low-coherence reflectometry and SRK/T formula for IOL power calculations, significant myopic shift was not observed after combined phacovitrectomy surgery in diabetic eyes with cataract and tractional retinal detachment. FINANCIAL DISCLOUSRE: NONE
