Abstract
Purpose::
to evaluate biocompatibility and visual outcomes after acrylic 1CU accomodative intraocular lens (IOL) implantation in unilateral Fuchs’ heterocromic iridocyclitis (FHI) - related cataract
Methods::
ten patients (3F,7M) aged 18 to 40 years (mean 32.6±6.48 years) with unilateral FHI and complicated cataract underwent phacoemulsification and 1CU accomodative IOL implantation. Main outcomes measures were: clinical course of FHI before and after surgery, uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), range of accomodation with subjective and objective (ultrasound biomicroscopy -UBM) methods, stereopsis and rate of complications were evaluated at time 7, 30, 180 days after surgery.
Results::
if compared with the preoperative reaction, chronic intraocular inflammation resulted unchanged at 30 and 180 days post-surgery. Seven days after surgery UDVA was ≥ 6/10 in 9 pts (90%), best corrected distance visual acuity (BCDVA) ≥ 8/10 in 9 pts (90%). Eight pts (80%) achieved an UNVA of J3 and 2 pts (20%) of J4.At 30 and 180 days the UDVA was ≥ 8/10 and BCDVA of 10/10 in 8 pts. Two patients showed BCDVA of 7/10 because of vitreal haze. Near visual acuity remained unchanged at days 30, while 180 days after surgery 60% had J2 or J3 UNVA and 90% J2 with or without near correction (mean: +1.5 diopter).Mean accomodation amplitude was 1.77±0.47 diopters (subjective near point) and mean decrease of ACD (UBM) was 0.6 ± 0.08 mm.A good stereopsis was achieved in all patients at 30 days and remained stable during the follow-up. At 180 days 2 pts (20%) developed posterior capsule opacification requiring YAG laser capsulotomy.
Conclusions::
The 1CU IOL implantation in young patients with unilateral FHI showed a good biocompatibility at medium term and provided satisfying visual rehabilitation in term of near visual acuity, accommodation and stereopsis
