Risk factors, complications, and results in extracapsular cataract extraction

Abstract

The incidence of perioperative and postoperative complications was comparable with those reported in other series. Factors that increased the risk of PCR + VL included pseudoexfoliation, diabetes mellitus, and a traumatic etiology. Previous glaucoma surgery and axial myopia of greater than 26.0 mm did not increase the PCR + VL risk. Loose or broken corneal sutures was a common finding that could be reduced substantially by planned suture removal.

Influence of age on conjunctival bacteria of patients undergoing cataract surgery

“…As the number of people who undergo cataract surgery after 75 years has increased in the last 20 years, [7][8][9][10][11][12][13][14][15] we compared the conjunctival bacteria of our patients aged 3-74 years with those aged 75-96 years, which is the main purpose of this study. A w 2 test was calculated for each conjunctival bacteria category in both age-groups.…”

“…9,[39][40][41][42][43] In spite of this difficulty, a literature review was carried out to investigate the relationship between age, sex, and PE incidence in other series of patients operated on for cataract. In most series the ages of the PE-affected patients are given but not the ages or sexes of the patients operated on for cataracts in the same period.…”

“…[8][9][10][11][12][13][14][15] For these reasons we study the preoperative conjunctival bacteria of patients undergoing cataract surgery at different stages of age. These bacteria are the main source of contamination of intraocular surgery, 16,17 and it is possible that sometimes bacteria produce inflammation that could be treated without developing infectious postsurgical endophthalmitis; but it could damage ocular tissues as well.…”

The conjunctival bacterial pattern of diabetics undergoing cataract surgery

“…2,8,9 This potential quantity of patients threatened with a poor visual acuity is a reason for preventing diabetics from PE. But, in addition, among the huge quantity of patients undergoing cataract operation, an increased PE incidence has often been associated with diabetes; [10][11][12][13][14] however, not many studies have been carried out to assess this fact and its causes.…”

Climatic influence on conjunctival bacteria of patients undergoing cataract surgery

“…1 Also in the same period, in Scotland, 2 a hospital infection control team reported more acute PE than expected after cataract surgery, according to the normal incidence. 3 Among the many risk factors involved in the PE pathogenesis, [4][5][6][7][8][9][10][11] it is difficult to assess the weight of climatic influence; however, as conjunctival bacteria are the main source of contamination in cataract surgery, 12,13 it is quite logical to expect that the prevalence of conjunctival bacteria determines the prevalence of the infectious PE. Today, the world-wide use of povidona iodine solution as a preoperative prophylaxis in cataract extraction 14 could provide homogeneity in the kind of bacteria that produce PE all over the world, which was impossible to detect when a great number of different prophylactic techniques were used.…”
