Abstract

PURPOSE

To determine prevalence, primary causes, and risk indicators of visual impairment in cataract-operated eyes.

DESIGN

Population-based cross-sectional study of adult Latinos.

PARTICIPANTS

Two hundred sixty-one participants with cataract extraction.

METHODS

Participants underwent an in-home interview and a comprehensive ophthalmologic examination. Visual impairment in the cataract-operated eye was defined by presenting visual acuity (PVA) of 20/40 or less or best-corrected visual acuity (BCVA) of 20/40 or less. The association of cataract extraction status (aphakic, pseudophakic) and severity of visual impairment was evaluated. Risk indicators associated with visual impairment by BCVA in the worse-seeing cataract-operated eye were evaluated.

MAIN OUTCOME MEASURES

Visual acuity, causes of visual impairment, and risk indicators associated with visual impairment.

RESULTS

Of the 261 participants with at least one cataract extraction and a complete clinical examination, 100 (38%) participants had undergone a unilateral extraction and 161 (62%) had undergone bilateral extractions. The prevalence of visual impairment was 41% (n = 107) defined by BCVA and 60.5% (n = 158) defined by PVA in the worse-seeing cataract-operated eye, and 32.2% (n = 136) defined by BCVA versus 48.1% (n = 203) defined by PVA in all cataract-operated eyes. Uncorrected refractive error, age-related macular degeneration, and diabetic retinopathy were the primary causes of visual impairment, accounting for 49% in worse-seeing cataract-operated eyes and 57% in all cataract-operated eyes. Self-reported history of glaucoma, barriers to eye care, and unmarried participants were independent risk indicators associated with visual impairment (P<0.05).

CONCLUSIONS

Despite cataract surgery, a significant proportion of participants had residual visual impairment. Refractive correction eliminated visual impairment in 15% to 20% of the participants, demonstrating the need for regular ophthalmologic examinations in cataract-operated patients.

摘要

目的

确定白内障手术后患眼视力损害的患病率、主要病因及风险指标。

设计

基于人群的成年拉丁裔横断面研究。

参与者

261例接受白内障摘除术的参与者。

方法

参与者接受了一次家庭访谈和一次全面的眼科检查。白内障手术后患眼的视力损害定义为最佳矫正视力（BCVA）为20/40或更低或矫正视力（PVA）为20/40或更低。评估白内障摘除状态（无晶状体眼、人工晶状体眼）与视力损害严重程度之间的关联。评估与视力较差的白内障手术后患眼的BCVA相关的视力损害风险指标。

主要观察指标

视力、视力损害原因以及与视力损害相关的风险指标。

结果

在261例至少接受过一次白内障摘除术且临床检查完整的参与者中，100例（38%）接受了单侧摘除，161例（62%）接受了双侧摘除。在视力较差的白内障手术后患眼中，BCVA定义的视力损害患病率为41%（n = 107），PVA定义的患病率为60.5%（n = 158）；在所有白内障手术后患眼中，BCVA定义的患病率为32.2%（n = 136），PVA定义的患病率为48.1%（n = 203）。未矫正的屈光不正、年龄相关性黄斑变性和糖尿病视网膜病变是视力损害的主要原因，在视力较差的白内障手术后患眼中占49%，在所有白内障手术后患眼中占57%。自我报告的青光眼病史、眼部护理障碍以及未婚参与者是与视力损害相关的独立风险指标（P<0.05）。

结论

尽管进行了白内障手术，但仍有相当比例的参与者存在残余视力损害。屈光矫正消除了15%至20%参与者的视力损害，这表明白内障手术患者需要定期进行眼科检查。
