To evaluate visual and refractive outcomes in eyes with a history of radial keratotomy (RK) implanted with the second-generation light-adjustable lens (LAL).
Private practice, multiple locations.
Retrospective, consecutive case series.
Eyes with a history of RK that underwent cataract surgery with implantation of the LAL and were targeted for emmetropia before lock-in were included. Data on the type and number of prior refractive surgeries were collected, in addition to the timing and number of postoperative adjustments. The primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity, and the percentage (%) of eyes within ±1.00 diopter (D), ±0.50 D, and ±0.25 D and of their refractive target.
94 eyes from 77 patients were included. 28% (n = 26) were a history of 4-cut RK, 12% (n = 11) were 6-cut RK, 55% (n = 52) were 8-cut RK, and 5% (n = 5) were 16-cut RK. Overall, 82% (n = 77) of all eyes achieved 20/25 UDVA or better, 74% (n = 70) of all eyes achieved UDVA of 20/20 or better, and 94% (n = 88) were correctable to 20/20 or better postoperatively. For refractive outcomes, 98% (n = 92) of eyes were within ±1.00 D of target, 88% (n = 83) were within ±0.50 D, and 69% (n = 65) were within ±0.25 D of preoperative refractive target.
Patients with a history of RK achieved favorable visual and refractive outcomes with the LAL. Postoperative light adjustments should be delayed to allow for refractive stabilization. The LAL is a promising option for post-RK patients who are motivated to obtain favorable uncorrected acuity after cataract surgery.
评估有放射状角膜切开术(RK)病史的眼睛植入第二代光可调人工晶状体(LAL)后的视觉和屈光效果。
多个地点的私人诊所。
回顾性连续病例系列。
纳入有RK病史且接受了LAL植入白内障手术并在锁定前目标为正视的眼睛。收集了既往屈光手术的类型和数量数据,以及术后调整的时间和次数。主要结局指标为未矫正远视力(UDVA)、矫正远视力,以及在±1.00屈光度(D)、±0.50 D和±0.25 D范围内且达到其屈光目标的眼睛百分比(%)。
纳入了77例患者的94只眼睛。28%(n = 26)有4切口RK病史,12%(n = 11)为6切口RK,55%(n = 52)为8切口RK,5%(n = 5)为16切口RK。总体而言,82%(n = 77)的眼睛达到20/25或更好的UDVA,74%(n = 70)的眼睛达到20/20或更好的UDVA,94%(n = 88)的眼睛术后可矫正至20/20或更好。对于屈光效果而言,98%(n = 92)的眼睛在目标±1.00 D范围内,88%(n = 83)在±0.50 D范围内,69%(n = 65)在术前屈光目标±0.25 D范围内。
有RK病史的患者使用LAL可获得良好的视觉和屈光效果。术后光调整应延迟以实现屈光稳定。对于有动力在白内障手术后获得良好未矫正视力的RK术后患者,LAL是一个有前景的选择。
