To report the safety and efficacy of treatment of hyperopic presbyopia with a new multifocal corneal laser in situ keratomileusis (LASIK) procedure, Supracor.
Mater Private Hospital, Dublin, Ireland.
Case series.
Bilateral LASIK using a multifocal corneal ablation profile was performed on consecutive hyperopic presbyopic patients with a manifest refraction spherical equivalent (MRSE) of +1.00 to +3.25 diopters (D) and a maximum 0.75 D difference between the MRSE and cycloplegic refraction. All patients were followed for a minimum of 6 months postoperatively. The main outcome measures were safety, efficacy in terms of uncorrected distance visual acuity (UDVA) and uncorrected reading ability (Vocational Reading Test), predictability, stability, patient satisfaction, and functioning at 6 months.
Forty-six eyes (23 patients) were treated. The mean binocular UDVA was 0.07 logMAR ± 0.12 (SD) at 6 months, with 91% having a binocular UDVA of 0.2 logMAR or better. Ninety-one percent had an uncorrected reading ability of N8 or better, and 93% were fully independent of reading glasses. Six percent lost 2 or more lines of corrected distance visual acuity (CDVA), with 100% maintaining a CDVA of 0.2 logMAR or better. Five patients (22%) required a retreatment in the dominant eye to enhance UDVA. Ninety-six percent were happy they had the procedure.
The procedure provided a high level of spectacle independence for near vision. The UDVA outcomes must be improved with nomogram adjustment to reduce the retreatment rate. Targeting emmetropia in the dominant eye and 0.50 D myopia in the nondominant eye may be an effective solution.

病例系列。
对连续的远视性老视患者进行双侧 LASIK,其明视屈光球镜等效(MRSE)为+1.00 至+3.25 屈光度(D),MRSE 与睫状肌麻痹验光之间的最大差异为 0.75 D。所有患者术后至少随访 6 个月。主要观察指标为安全性、未经矫正的远视力(UDVA)和未经矫正的阅读能力(职业阅读测试)的有效性、预测性、稳定性、患者满意度以及 6 个月时的功能。
共治疗 46 只眼(23 例)。6 个月时双眼平均 UDVA 为 0.07 对数视力表(logMAR)±0.12(标准差),91%的双眼 UDVA 为 0.2 logMAR 或更好。91%的患者有 N8 或更好的未矫正阅读能力,93%的患者完全不需要阅读眼镜。6%的患者丧失 2 行或更多的矫正远视力(CDVA),但 100%的患者保持 CDVA 为 0.2 logMAR 或更好。5 例(22%)患者在主导眼行二次治疗以提高 UDVA。96%的患者对该手术感到满意。
该手术为近视力提供了较高水平的眼镜独立性。需要通过视力表调整来提高 UDVA 结果,以降低再次治疗的比率。在主导眼实现正视和非主导眼 0.50 D 近视可能是一种有效的解决方案。
