Reduction of Intraocular Pressure after Phacoemulsification and Aspiration with Intraocular Lens Implantation

Abstract

We prospectively evaluated the pre- and postoperative intraocular pressures (IOP) of 1,118 cataract patients. All surgical procedures were performed by the same skilled surgeon using the same method of phacoemulsification and aspiration with intraocular lens implantation. The mean ± SE preoperative IOP was 13.29 ± 0.12 mm Hg, while the mean IOP values were 10.87 + 0.12, 9.94 ± 0.09, and 10.43 + 0.14 mm Hg 1, 3, and 6 months, respectively, after surgery. When the preoperative IOP was in the low 20 s, a decrease of approximately 40% was achieved. The present study shows that the IOP decreased postoperatively to a greater extent than previously considered, and the rate of decrease was dependent on the initial measurement.

Ten-Year Follow-Up of Intraocular Pressure after Phacoemulsification and Aspiration with Intraocular Lens Implantation Performed by the Same Surgeon

“…These data differ considerably from the 6-month pro spective data of the same surgeon, in that the reduction was approximately 36% when the initial IOP was approximately 25 mm Hg [3], whereas the reduction was much smaller when the initial IOP was within borderline control. Our 6-nionth prospective study showed that the IOP decreased postoperativcly to a greater extent than considered, and the rate o f the decrease was dependent on the initial measure ment.…”

“…Following a 6-month prospective study performed by one skilled surgeon using the same method [3], we showed that the IOP decreased postoperatively to a greater extent than previously considered, and the rate of the decrease was dependent on the initial measurement. Therefore, we con- eluded that we should first offer patients the benefit of lOL implantation.…”

“…A half-depth, 6-mm-long corneoscleral incision was made at the 10.30-o'clock position [3]. Until 1991. a 10-0 Mersilene horizontal suture was used to close the section at one end in standard suture fash ion.…”

“…Phacoemulsification and aspiration (PEA) procedures with posterior chamber intraocular lens (PCIOL) implanta tion affect intraocular pressure (IOP) [1][2][3]. Some studies document an increase in IOP following cataract surgery with or without glaucoma [1,[3][4][5].…”

“…Some studies document an increase in IOP following cataract surgery with or without glaucoma [1,[3][4][5]. The rate of change may depend on the method and the size of the incision of cataract surgery [1,3,4] and the skill with which the surgery is exe cuted [6].…”
