Reduction of pupillary constriction during cataract surgery using suprofen
Archives of Ophthalmology (Chicago, Ill. : 1960)
|March 1, 1986
Summary
Suprofen effectively prevented pupil constriction during cataract surgery, leading to larger pupil sizes and easier intraocular lens implantation. This nonsteroidal anti-inflammatory agent demonstrated significant benefits over placebo.
Area of Science:
- Ophthalmology
- Pharmacology
Background:
- Pupillary constriction can complicate cataract surgery.
- Maintaining adequate pupil dilation is crucial for intraocular lens (IOL) implantation.
Purpose of the Study:
- To evaluate the efficacy of suprofen in preventing pupillary constriction during cataract surgery.
- To assess the impact of suprofen on pupil size and ease of IOL implantation.
Main Methods:
- A double-masked, multicenter, clinical study.
- 1.0% suprofen or placebo instilled pre-surgery with standard mydriatics/cycloplegics.
- Comparison of pupillary area and surgeon's subjective evaluations between groups.
Main Results:
- Suprofen (209 patients) was significantly more effective than placebo (203 patients) in maintaining pupil dilation.
- Mean pupillary area was 6.3 sq mm larger (20% increase) with suprofen.
- Surgeons favored suprofen for pupil size adequacy and ease of IOL implantation.
Conclusions:
- Suprofen is an effective agent for maintaining pupil dilation during cataract surgery.
- Suprofen facilitates intraocular lens implantation by ensuring adequate pupil size.
