Results after intracapsular extraction: the atonic pupil

Satisfactory visual results are reported in a series of 80 consecutive patients who underwent intracapsular cataract extraction with a four- or three-loop Binkhorst lens replacement. Nearly 50% of patients could see 20/30 or better unaided. However, results in the under 70 age group tend to be marred by macular edema, and in the over 80 age group by corneal edema, the latter occasionally being the result of lens instability because of an atonic pupil.
