Summary

Capsule contraction syndrome (CCS) is a common complication after cataract surgery. Performing larger capsulorhexis and using specific IOLs can help prevent CCS.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Cataract Surgery

Background:

  • Capsule contraction syndrome (CCS) is characterized by significant reduction in the anterior capsulotomy diameter, capsular bag, and potential intraocular lens (IOL) displacement post-extracapsular cataract extraction.
  • CCS is more prevalent in cases of pseudoexfoliation, advanced age, uveitis, pars planitis, and myotonic muscular dystrophy.

Observation:

  • A study analyzed 5965 eyes undergoing cataract surgery between 1994 and 1997.
  • Two surgical techniques were compared: phacoemulsification with continuous curvilinear capsulorhexis (3385 eyes) and extracapsular cataract extraction with "can opener" capsulotomy (2580 eyes).

Findings:

  • Twenty cases of clinically evident CCS were identified.
  • Contributing factors included intensive postoperative inflammation (5 cases), advanced age (4 cases), pseudoexfoliation syndrome (2 cases), myotonic dystrophy (1 case), and ectopia lentis (2 cases).
  • Interventions for CCS included surgical removal of the anterior capsule (4 cases), radial relaxing tears (3 cases), and secondary anterior capsulotomy with Nd:YAG laser (3 cases).

Implications:

  • For high-risk cases of CCS, employing a large-diameter capsulorhexis is recommended.
  • Implanting IOLs designed for maximal peripheral capsular bag expansion may mitigate CCS occurrence.
