Intraocular pressure after intracapsular cataract extraction.
We studied the incidence of postoperative intraocular pressure elevations in 42 patients following intracapsular cataract extraction with alpha-chymotrypsin (1:5,000) and noted 17% to develop pressures greater than 30 mm Hg and 38% greater than 24 mm Hg within a 48-hour time interval. Additionally, we studied the effect of a single immediate postoperative instillation of timolol maleate 0.5%; this was associated with a slight reduction of intraocular pressure at the three- and six-hour time intervals, but did not eliminate the pressure spikes.
