In Western Australia during the period 1 January 1976 to 31 December 1987 1089 eyes of 1044 patients in hospital were operated upon for primary rhegmatogenous retinal detachment due to causes other than penetrating trauma. Of these eyes 295 (27%) were aphakic or pseudophakic. During this period the annual number of cataract operations in the State increased by a factor of 245%, while aphakic and pseudophakic retinal detachment operations rose by only 55%. The declining risk of retinal detachment following cataract surgery is attributed to improvements in microsurgical techniques. In 1983 and 1984 the incidence of aphakic and pseudophakic retinal detachments dropped significantly (p less than 0.05). At about this time extracapsular cataract surgery became widespread in the State, and this may explain the observed fall in retinal detachment operations. Since 1984 the incidence has risen owing to the rapidly increasing prevalence of pseudophakia in the resident population.
在1976年1月1日至1987年12月31日期间，西澳大利亚州有1044名住院患者的1089只眼睛因穿透性外伤以外的原因接受了原发性孔源性视网膜脱离手术。其中295只眼睛（27%）为无晶状体眼或人工晶状体眼。在此期间，该州白内障手术的年数量增长了245%，而无晶状体眼和人工晶状体眼视网膜脱离手术仅增长了55%。白内障手术后视网膜脱离风险的降低归因于显微手术技术的改进。1983年和1984年，无晶状体眼和人工晶状体眼视网膜脱离的发生率显著下降（p<0.05）。大约在这个时候，囊外白内障手术在该州广泛开展，这可能解释了视网膜脱离手术数量的下降。自1984年以来，由于常住人口中人工晶状体眼的患病率迅速上升，发病率有所上升。
