Effect of postoperative mydriatics on the iris
1Ophthalmology Department, Ninewells Hospital and Medical School, Dundee, Scotland.
Purpose:
To assess the role postoperative mydriatics play after extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (IOL) implantation in causing iris modifications and in controlling inflammation.
Setting:
Outpatients Department, Ninewells Hospital, Dundee, Scotland.
Methods:
The prospective study comprised 136 patients who had standardized ECCE. Half the patients used a mydriatic for 2 weeks postoperatively. Anterior chamber activity, pain, and eye redness were evaluated at 2 weeks postoperatively; pupil shape, peripheral anterior synechias, IOL position, and iris adhesions, at 6 weeks.
Results:
Iris-lens adhesions were significantly more common in the group using a mydriatic. There was no difference between the two groups in postoperative inflammation.
Conclusion:
Mydriatics should not be used routinely after ECCE with posterior chamber IOL implantation.
