Angle-supported intraocular lenses: a goniophotographic study.
Ophthalmology
|July 1, 1984
Summary
Cataract surgery with certain intraocular lenses (IOLs) like the "Azar 91Z" can lead to iris complications. Early detection via gonioscopy is recommended for these IOLs.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Cataract surgery often involves intraocular lens (IOL) implantation.
- Complications related to IOL haptic-iris interaction can impact patient outcomes.
Purpose of the Study:
- To prospectively evaluate the incidence of iris-haptic synechia and haptic burial after cataract surgery.
- To compare the complication rates between IOLs with different designs.
Main Methods:
- Prospective follow-up of 28 eyes using goniophotography post-cataract surgery.
- Categorization of eyes into three groups: no IOL, "Azar 91Z" IOL, and Cilco "Optiflex" IOL.
Main Results:
- High rates of iris-haptic synechia or burial observed with the "Azar 91Z" lens (90%) and Cilco "Optiflex" lens (37.5%).
- Complications predominantly occurred in the inferior angle and were detectable as early as 4 weeks postoperatively.
Conclusions:
- Preoperative gonioscopy is advised before removing specific IOLs due to potential iris complications.
- Surgical option of cutting buried haptics and leaving them in situ may mitigate anterior segment trauma.
