Abstract:
PURPOSE: To observe the effect of phacoemulsification and
intraocular lens (IOL) implantation with or without lens capsular
tension ring (CTR) on retinitis pigmentosa (RP) combined with cataract
patients.
DESIGN: Retrospective case series study.
METHODS: 63 cases (84 eyes) of RP with cataract were collected,
including 30 males and 33 females. Phacoemulsification with 3.0 mm clear
corneal incision was performed in all the patients.
IOL and CTR implantation was
performed in 44 eyes, and IOL implantation alone was performed in 40
eyes. All cases were followed up at 1 week and 1, 3, 6 months after the
surgery to compare the best corrected visual acuity (BCVA), intraocular
pressure (IOP), corneal endothelial
cell count (ECC) and complications before and after the surgery.
RESULTS: All surgeries were successfully completed by the same
physician, and IOL and CTR were all implanted in capsule without
complications. The BCVA at 6 months after surgery was 0.91±0.88
LogMAR. It improved a little compared
with the BCVA(1.3±0.7LogMAR) before surgery and there was statistically
significant difference (P=0.003).
Four cases of capsule contraction syndrome (CCS) occurred in no CTR
implantation group and there was no CCS in CTR group. There was
statistically significant difference in the incidence of CCS between two
groups(P=0.047).
CONCLUSIONS : Phacoemulsification for RP combined with cataract
is safe and reliable, and CTR implantation is helpful in reducing the
complications caused by capsule contraction.
