Long-term change in intraocular pressure after extracapsular cataract extraction with posterior chamber intraocular lens implantation versus phacoemulsification with posterior chamber intraocular lens implantation in Indians

Abstract

Purpose:The purpose of the study is to evaluate the long-term changes in intraocular pressure (IOP) after extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PCIOL) implantation versus phacoemulsification with PCIOL implantation in otherwise normal cataract patients in India.Materials and Methods:The study was conducted in the Department of Ophthalmology, King George's Medical College, Lucknow between August 2000 and August 2001. One hundred and seventeen eyes of 115 patients were included in the study. 84 patients were randomly selected for ECCE with PCIOL implantation (ECCE group) and 31 patients were selected for phacoemulsification with PCIOL implantation (Phaco group). IOP was measured pre-operatively and post-operatively, from the 1st month to the 12th month. Statistical significance was indicated by P > 0.05.Results:There was a mean fall in IOP of 2.70 mm Hg (19.74%) in the ECCE group and 2.74 mm Hg (20.57%) in the phaco group. The decrease in the mean post-operative IOP from baseline was statistically significant (P > 0.01) at the end of 2 months in both groups. There was no statistically significant difference in post-operative IOP at any visit between groups (P < 0.05, all post-operative visits). After 4th monthpost-operatively, the IOP was mostly stable, but it was significantly lower than the pre-operative IOP.Conclusion:Significant IOP reduction may be expected after cataract surgery with either ECCE or phacoemulsification with IOL implantation. The lowering of IOP became statistically significant at about 2 months post-operatively, but became almost stable after the 4th month.

Intraocular Pressure Reduction after Phacoemulsification versus Manual Small-Incision Cataract Surgery

“…Supporting this idea, Lee et al 26 found that the amount of ultrasound energy delivered to the eye during phacoemulsification (expressed as cumulative dissipated energy) had no influence on the magnitude of IOP reduction after phacoemulsification. Also, in a study by Pal et al 6 comparing extracapsular cataract extraction (ECCE) and phacoemulsification in 117 Indian eyes, the mean IOP reduction at 4 to 6 months was found to be identical to our values and similar between the ECCE and phacoemulsification groups. However, this study was not a randomized masked clinical trial and did not evaluate AS OCTebased angle parameters.…”

“…However, a previous study (8) reported that the incidence of early postoperative ocular hypertension after PE surgery was 8.4%, in contrast to 29.8% after ECCE surgery. This significantly smaller incidence of ocular hypertension after PE compared with ECCE is consistent with the results of Pal et al (19).…”

“…A significant IOP drop was observed in both groups at 2 months postoperatively. Intraocular pressure values stabilized after month 4 and remained significantly lower as compared to baseline [ 3 ].…”
