Summary

A dislocated intraocular lens (IOL) within the capsular bag occurred in a myopic patient with a large anterior segment. The dislocated IOL was successfully replaced with a sulcus-sutured posterior chamber IOL.

Area of Science:

  • Ophthalmology
  • Surgical Case Reports
  • Intraocular Lens Technology

Background:

  • Cataract surgery often involves intraocular lens (IOL) implantation.
  • Capsular bag dislocation of an IOL is a rare but significant complication.
  • Patient factors like myopia and anterior segment size may influence IOL stability.

Observation:

  • A standard 5 mm x 6 mm phaco profile IOL was completely dislocated within the capsular bag.
  • The dislocation was noted on the fifth postoperative day in a myopic patient with a large anterior segment.
  • The patient's anatomical characteristics may have contributed to the IOL instability.

Findings:

  • Complete dislocation of an intraocular lens within the capsular bag was observed.
  • Successful management involved explantation of the dislocated IOL.
  • A secondary posterior chamber IOL was implanted and secured at the ciliary sulcus.

Implications:

  • This case highlights the importance of considering patient-specific factors in IOL selection and fixation.
  • Management strategies for dislocated IOLs include repositioning or secondary implantation.
  • Understanding risk factors for IOL dislocation can improve surgical outcomes and patient safety.
