BACKGROUND: In this retrospective study the postoperative alteration of intraocular pressure after cataract extraction and posterior chamber lens implantation was analyzed statistically. The influence on intraocular pressure between different positions of the loops (sulcus versus bag) was compared.
PATIENTS AND METHOD: The posterior chamber lens implantation was performed on 267 eyes with 129 sulcus implanted and 138 in-the-bag implanted intraocular lenses. The average age of the patients was 74.8 respectively 71.9 years, with an equal ratio of sex. In surgery the viscoelastic experimentation of the nucleus was done via corneoscleral cut. A x-crossed suture sealed the corneoscleral wound followed by subconjunctival injection of corticosteroids. The postoperative medication for 4-6 weeks consisted of a corticosteroid and antibiotic combination.
RESULTS: The average intraocular pressure of the sulcus implanted respectively in the bag implanted intraocular lenses increased from 15.4 mm Hg respectively 15.9 mm Hg preoperatively to 16.3 respectively 15.8 mm Hg at the first postoperative day. After two months the intraocular pressure decreased to 14.6 respectively 14.1 mm Hg. That means a pre- to postoperative difference of -0.8 respectively -1.8 mm Hg.
CONCLUSIONS: In summary both groups showed a slight decrease in average intraocular pressure after two months. In comparison to the sulcus implanted intraocular lens the decrease of intraocular pressure was more than 1 mm Hg in case of the in the bag implanted lens. This decrease was statistically significant but may be considered of less clinical interest.
