Abstract
PRCIS
Early lensectomy in patients presenting pseudoexfoliation (PXF) in an asymmetric clinical stage resulted in effective, safe, and predictable long-term results. Good intraocular pressure (IOP) was found, thus it might be considered as a possible surgical approach in these patients.
PURPOSE
The purpose of this study is to assess the long-term effectiveness, predictability, and safety of cataract surgery performed in patients with capsular PXF at an early stage of the disease.
MATERIALS AND METHODS
This retrospective, comparative study included PXF patients who underwent phacoemulsification with hydrophobic acrylic intraocular lens implantation in both eyes with a postoperative follow-up ≥5 years. Patients were classified in 2 groups: symmetric PXF (n=102) and asymmetric PXF (n=59). Preoperative and postoperative uncorrected and corrected distance visual acuity, manifest refraction, IOP, number of hypotensive drugs, visual field mean deviation, and the incidence of complications were registered.
RESULTS
The mean follow-up time was 8.5±2.8 years. Six months after cataract surgery, monocular uncorrected and corrected distance visual acuity were 0.3±0.4 and 0.1±0.3 logMAR, respectively, for the symmetric PXF, and 0.2±0.2 and 0.1±0.2 logMAR, respectively, for the asymmetric group. Total 95% and 96% of eyes were within ±1.00D in symmetric and asymmetric groups, respectively. At the final follow-up, IOP decreased only in the asymmetric group (P=0.004), with a reduction in the number of medications in both eyes (P<0.001). Mean deviation changed from -8.8 to -11.6 dB in the symmetric group (P<0.001), and from -5.0±6.2 to -7.9±10.6 dB (P=0.42) in the asymmetric group. Intraoperative complications were only registered in the symmetric group: 7 (3.4%; P=0.04). Ten cases (4.9%) of late intraocular lens dislocation were found, all from the symmetric group (P=0.03).
CONCLUSIONS
Early lensectomy in patients with PXF before its symmetric presentation resulted in effective, safe, and predictable long-term results.
