To assess the incidence and visual morbidity of lens matter dislocation during phacoemulsification and the relationship between this complication and surgical experience.
Teaching and district general hospitals.
A multiple-choice questionnaire was sent to members of the Northern and Midlands Ophthalmological Societies. They were asked about the incidence of lens matter dislocation, the visual outcome of the cases, and their surgical experience.
Forty-seven of the 177 survey respondents (26.5%) were using phacoemulsification. The incidence of lens matter dislocation was 1.1%; 49.0% of the surgeons had experienced at least one case. The incidence increased significantly when surgeons assessed their expertise with phacoemulsification toward the expert end of the scale. Final visual acuity was worse than 6/12 in 35.0% of cases.
The incidence of lens matter dislocation with phacoemulsification is significant and related to an incorrect assessment of expertise by the surgeons. The considerable visual morbidity associated with this complication can be minimized using the management strategy discussed.
评估白内障超声乳化吸除术中晶状体物质脱位的发生率及视觉损害情况，以及该并发症与手术经验之间的关系。
教学医院和地区综合医院。
向北部和中部眼科协会成员发送了一份多项选择题问卷。询问他们晶状体物质脱位的发生率、病例的视觉转归以及他们的手术经验。
177名调查受访者中有47名（26.5%）使用白内障超声乳化吸除术。晶状体物质脱位的发生率为1.1%；49.0%的外科医生至少经历过1例。当外科医生将其白内障超声乳化技术专长评定为接近专家水平时，发生率显著增加。35.0%的病例最终视力低于6/12。
白内障超声乳化吸除术中晶状体物质脱位的发生率较高，且与外科医生对自身专长的错误评估有关。采用所讨论的管理策略可将与该并发症相关的严重视觉损害降至最低。
