Clinical Trial: Late Dislocation of Intraocular Lens (IOL) Following Cataract Surgery: an Evaluation of Two Different Surgical Methods

Study Status: Active, not recruiting
Recruit Status: Active, not recruiting
Study Type: Interventional

Official Title:

Brief Summary: In this prospective, randomized study The investigators will include 80 patients with late intraocular lens (IOL) dislocation in the capsular complex, after cataract surgery. To obtain normal visual function, these patients needs surgery. Today, there are two different methods used for this condition; scleral suturing of the capsular complex or exchange of IOL to an iris-fixated IOL (Verisyse). In this study the investigators will look for advantages and dis-advantages for these two methods.

Detailed Summary:
Sponsor: Oslo University Hospital

Current Primary Outcome:

  • Best corrected visual acuity [ Time Frame: 6 months ]
  • Intraocular pressure (IOP) [ Time Frame: 6 months ]
  • Endothelial density [ Time Frame: 6 months ]
  • Postoperative complications [ Time Frame: 6 months ]


Original Primary Outcome: Compare intra- and post-operative complications/results between the two methods [ Time Frame: 1 year ]

Parameteres that will be measured: Best corrected visual aquity, intraocular pressure (IOP), endothelial density, keratometry, postoperative IOP rise, questionare about visual function (VF-14), measure IOL's location with slit lamp and Pentacam.


Current Secondary Outcome:

  • Keratometry [ Time Frame: 6 months ]
  • Questionaire Visual function (VF-14) [ Time Frame: 6 months ]
    About visual function
  • IOL location [ Time Frame: 6 months ]
    Measure IOL's location with slit lamp and Pentacam.
