研究目的
To compare the safety, efficacy, and predictability of femtosecond laser–enabled anterior penetrating and intrastromal arcuate incisions for the correction of preoperative astigmatism at the time of cataract surgery.
研究成果
Both anterior penetrating and intrastromal femtosecond laser arcuate incisions were safe and effective through a 6-month follow-up and significantly reduced corneal cylinder postoperatively; however, the anterior penetrating incisions showed clinically better results compared with the intrastromal incisions.
研究不足
Relatively small sample size and short follow-up. Potential variability in results due to factors like eye tilt, tissue bridges, and individual healing factors.
1：Experimental Design and Method Selection:
Prospective randomized comparison study.
2：Sample Selection and Data Sources:
50 eyes of 50 patients with age-related cataract and astigmatism of
3：75 to 00 diopters. List of Experimental Equipment and Materials:
CATALYS Precision System (Johnson & Johnson Vision Care, Inc.), Pentacam HR (Oculus Optikger?te GmbH), specular microscopy (Tomey Corp.), macular optical coherence tomography (OCT) (OptoVue, Inc.), IOL Master 700 (Carl Zeiss Meditec AG).
4：Experimental Procedures and Operational Workflow:
Femtosecond laser–assisted cataract surgery with either anterior penetrating or intrastromal arcuate incisions.
5：Data Analysis Methods:
Vector analysis of astigmatism using the Alpins method with the ASSORT software.
