Complications of sulcus placement of single-piece acrylic intraocular lenses: recommendations for backup IOL implantation following posterior capsule rupture.

Author information

Altos Eye Physicians, Los Altos, California 94024, USA.



To describe complications arising from sulcus placement of single-piece acrylic (SPA) intraocular lenses (IOLs), evaluate IOL options for eyes that lack adequate capsule support, and examine the appropriateness of various IOL designs for sulcus placement.


University and private anterior segment surgery practices.


Patients referred for complications of SPA IOLs in the ciliary sulcus from 2006 and 2008 were identified. Demographic information, examination findings, and complications of the initial surgery were recorded. Details of surgical interventions and the most recent corrected distance visual acuity (CDVA) were noted. A thorough review of the literature was undertaken to analyze options for IOL placement.


Complications of sulcus SPA IOLs included pigment dispersion, iris transillumination defects, dysphotopsia, elevated intraocular pressure, intraocular hemorrhage, and cystoid macular edema. Two patients in the series of 30 patients experienced 1 complication; 8 experienced 2 complications; 13 experienced 3 complications; 4 experienced 4 complications; and 2 experienced 5 complications. Twenty-eight eyes (93%) required surgical intervention; IOL exchange was performed in 25 (83%). Postoperatively, the mean CDVA improved, with most eyes attaining 20/20.


Intraocular lenses designed solely for the capsular bag should not be placed in the ciliary sulcus. Backup IOLs in appropriate powers, sizes, and designs should be available for every cataract procedure. The development, investigation, and supply of IOLs specifically designed for placement in eyes that lack adequate capsule support represent clinically important endeavors for ophthalmology and the ophthalmic industry.
