Acuity and Quality of Vision in Eyes with Epithelial Basement Membrane Dystrophy after Regular Pseudophakia.

PURPOSE

This retrospective case-control study was conducted to quantitatively and qualitatively assess the visual impairment in eyes with Epithelial Basement Membrane Dystrophy (EBMD) after regular cataract surgery.

METHODS

EBMD pseudophakic eyes were compared with matched pseudophakic eyes free from surface disorders. At least 3 weeks after surgery we evaluated uncorrected and best-corrected distance visual acuity (UDVA and CDVA), objective aberrometry, Point Spread Function (PSF), Modulation Transfer Function (MTF), and patient complaints.

RESULTS

Twenty-five EBMD eyes and 25 control eyes (13 patients per group) were included. Nine patients per group had a monofocal IOL, and four patients had a trifocal IOL. All the EBMD patients complained of postoperative blurred vision with ocular discomfort; intensive use of lubricants induced subjective improvement only in eyes with monofocal IOLs. Postoperative mean UDVA was 0.19 ± 0.16 LogMAR in the EBMD eyes and 0.11 ± 0.04 LogMAR in the control group ( = 0.016). Mean CDVA was 0.18 ± 0.15 LogMAR in the EBMD eyes and 0.06 ± 0.04 LogMAR in the control eyes ( = 0.001). The PSF curve width was significantly worse in the EBMD group ( < 0.001). The MTF cut-off value was lower in the EBMD group than in the control group ( < 0.001).

CONCLUSION

After cataract removal, eyes with EBMD had significantly lower UDVA and CDVA than controls. All the aberrometric parameters were significantly worse in EBMD cases. EBMD patients complained about their postoperative visual outcome, while control patients did not.
