The purpose of this study was to compare early visual outcomes, epithelial healing, and stromal haze between transepithelial photorefractive keratectomy (Trans-PRK) using smart pulse technology (SPT) with traditional Trans-PRK.
This study is a retrospective, comparative study conducted at a private eye center in "Riyadh, Saudi Arabia," investigating myopic patients who underwent either Trans-PRK with SPT (study group) or traditional Trans-PRK (control group). The patients were assessed preoperatively and followed up at 1 week and 2 months postoperatively. The main outcomes included uncorrected distance visual acuity (UDVA), corneal haze, and corneal epithelial defect.
This study included 501 eyes, of them, 222 eyes (44.3%) underwent Trans-PRK with SPT. The UDVA in the study group was significantly better 1 week postoperatively ( < 0.05). For the 2-month follow-up visits, there was no significant difference between the groups. Epithelium healing and stromal haze were comparable in the two groups without significant differences between them.
Transepithelial photorefractive keratectomy with SPT yielded better short-term visual outcomes than traditional Transepithelial photorefractive keratectomy.
本研究旨在比较使用智能脉冲技术（SPT）的经上皮光屈光性角膜切削术（Trans-PRK）与传统Trans-PRK之间的早期视觉效果、上皮愈合及基质 haze。
本研究是在沙特阿拉伯利雅得一家私立眼科中心进行的一项回顾性比较研究，调查接受SPT的Trans-PRK（研究组）或传统Trans-PRK（对照组）的近视患者。患者在术前进行评估，并在术后1周和2个月进行随访。主要结果包括未矫正远视力（UDVA）、角膜 haze 和角膜上皮缺损。
本研究纳入501只眼，其中222只眼（44.3%）接受了SPT的Trans-PRK。研究组术后1周的UDVA明显更好（<0.05）。在2个月的随访中，两组之间无显著差异。两组的上皮愈合和基质 haze 相当，无显著差异。
与传统经上皮光屈光性角膜切削术相比，使用SPT的经上皮光屈光性角膜切削术产生了更好的短期视觉效果。
