Literature data confirm the existence of different opinions about the nature of changes in intraocular pressure after cataract extraction. However, assessment of the risk factors significance for complications and prediction their occurrence in the postoperative period are still unresolved issues. Average statistical norm can still entail a persistent increase in IOP after cataract surgery. Purpose : to study the frequency of persistent increase in IOP after cataract surgery with a statistically normal level of IOP depending on the ratio of the preoperative level of IOP with its individual norm. Methods : The clinical study was based on the analysis of 69 phacoemulsifications and posterior chamber intraocular lens implantations with a preoperative IOP level within the average statistical norm (IOP 0.5). GROUP 2. After a year decrease in IOP was recorded in 11 eyes (52.4 %). In 10 eyes (47.6 %) IOP remained unchanged. GROUP 3 The initial IOP level before surgery was on average 17.9 ± 1.4. One year later, a decrease in IOP was recorded in 6 eyes (40.9 %). In 8 eyes (22.7 %) IOP remained unchanged. Conclusions . When planning cataract surgery the indicator of real compensation is the level of ophthalmotonus, which does not exceed the individual norm. IOP exceeding the individual norm indicates a high probability of a persistent increase in IOP after cataract surgery.
