摘要

目的:介绍最初使用 FEMTO LDV Z8 平台(Ziemer 眼科系统公司)进行角膜屈光小体摘除术(KLEx)治疗的 102 只眼睛的结果,并详细说明所采用的手术方法:这是对贝鲁特美国大学医学中心接受 KLEx 治疗的 53 名患者的 102 只眼睛进行的回顾性分析。对术后 1 周、1、3、6 和 12 个月的视力、屈光度、地形图和像差参数进行了评估:术前平均球面等效屈光度(SEQ)为-4.11 ± 1.82屈光度(D)(范围:-10.00至-1.625 D),术前平均圆柱度为-0.75 ± 0.65 D(范围:-3.00至0.00 D)。术后 1 周的平均 SEQ 为 0.06 ± 0.54 D(范围:-2.88 至 +1.00 D),12 个月的平均 SEQ 为 -0.04 ± 0.26 D,95.6% 的眼睛 SEQ 在 ±0.50 D 以内,100% 的眼睛 SEQ 在 ±1.00 D 以内。术后 12 个月时,共有 96.7% 的眼睛的未矫正远视力 (UDVA) 达到 20/20。50%的眼睛矫正后的远距离视力(CDVA)提高了一条或一条以上,5 只眼睛(5.4%)降低了一条,没有眼睛降低两条或两条以上。没有出现抽吸损失,所有提取的皮孔都完好无损,没有撕裂:结论:使用 FEMTO LDV Z8 平台应用 KLEx 可获得安全有效的结果,与屈光手术领域以前使用和接受的成熟的皮孔提取模式和飞秒激光辅助激光原位角膜磨镶术相当。[J Refract Surg. 2024;40(11):e898-e905.].

Keratorefractive Lenticule Extraction Using the Ziemer FEMTO LDV Z8 Platform (CLEAR): One-Year Results.

Purpose: To present the outcomes and detail the surgical procedure employed in the initial 102 eyes treated with keratorefractive lenticule extraction (KLEx) using the FEMTO LDV Z8 platform (Ziemer Ophthalmic Systems).

Methods: This was a retrospective analysis of 102 eyes of 53 patients treated with KLEx at the American University of Beirut Medical Center. Visual, refractive, topographic, and aberrometric parameters were evaluated 1 week and 1, 3, 6, and 12 months postoperatively.

Results: Mean preoperative spherical equivalent refraction (SEQ) was -4.11 ± 1.82 diopters (D) (range: -10.00 to -1.625 D) and mean preoperative cylinder was -0.75 ± 0.65 D (range: -3.00 to 0.00 D). Postoperatively, the mean SEQ was 0.06 ± 0.54 D (range: -2.88 to +1.00 D) at 1 week and -0.04 ± 0.26 D at 12 months and was within ±0.50 D in 95.6% and ±1.00 D in 100% of eyes. A total of 96.7% of eyes had an uncorrected distance visual acuity (UDVA) of 20/20 at 12 months postoperatively. Fifty percent gained one or more lines of corrected distance visual acuity (CDVA), 5 eyes (5.4%) lost one line, and none lost two or more lines. No suction losses were encountered and all extracted lenticules were intact without tears.

Conclusions: The application of KLEx using the FEMTO LDV Z8 platform yields safe and effective outcomes, aligning comparably with established modes of lenticule extraction and femtosecond laser-assisted laser in situ keratomileusis procedures previously employed and accepted within the field of refractive surgery.

期刊介绍: The Journal of Refractive Surgery, the official journal of the International Society of Refractive Surgery, a partner of the American Academy of Ophthalmology, has been a monthly peer-reviewed forum for original research, review, and evaluation of refractive and lens-based surgical procedures for more than 30 years. Practical, clinically valuable articles provide readers with the most up-to-date information regarding advances in the field of refractive surgery. Begin to explore the Journal and all of its great benefits such as: • Columns including “Translational Science,” “Surgical Techniques,” and “Biomechanics” • Supplemental videos and materials available for many articles • Access to current articles, as well as several years of archived content • Articles posted online just 2 months after acceptance.
