The Effect of Extracapsular Cataract Extraction and Posterior chamber Lens Implantation on Intraocular Pressure
|
|

Abstract
|
|
|
We studied the change in intraocular pressure (IOP) in 15 consecutive cataract patients who underwent extracapsular cataract extraction and posterior chamber lens implantation between Feb. 1993 and Apr. 1993 to evaluate the effect of this surgery
on
postoperative IOP. To evaluate the clinical usefulness of non-contact tonometer, the intraocular pressures were measured with Kowa non-contact tonometer (TM-2000, Japan) as well as Goldmann applanation tonometer.
There was a decrease in IOP of 3.4±2.9mmHg (p<0.001) 3 months after this surgery and the intraocular pressure differences between pseudophakic eyes and contralateral phakin eyes at 3 months postoperatively were 2.4±3.8mmHg (p<0.05).
The correlation coefficient between non-contact tonometer and Goldmann tonometer was 0.8876 (p=0.001) in the postoperative 76 eyes.
Therefore, out results suggest that extracapsular cataract extraction and posterior chamber lens implantation alone can be a useful surgical method in cataract patient with ocular hypertension, and non-contact tonometer was relatively accurate in
measuring the postoperative intraocular pressure.
