研究目的
To compare the pain and the duration of a panretinal photocoagulation (PRP) session using a conventional multispot laser versus the Navilas? laser.
研究成果
PRP sessions using the Navilas laser were significantly faster and less painful than with a conventional multispot laser. The pre-planning feature in Navilas provides a high quality output with equidistant spots, lack of gaps or doubled patterns, and lower application time and pain experience for the patient.
研究不足
The main limitations include the small sample size and the lack of blinding of the operators and patients toward the treatment system.
1：Experimental Design and Method Selection:
The study was a prospective comparison of PRP sessions using a conventional multispot laser and the Navilas laser in treatment-na?ve patients with diabetic retinopathy. Similar laser parameters were used for both treatments.
2：Sample Selection and Data Sources:
Sixteen patients (32 eyes) with bilateral pre-PDR or PDR eligible for PRP were enrolled. Exclusion criteria included intravitreal hemorrhage or media opacities inhibiting laser treatment.
3：List of Experimental Equipment and Materials:
Conventional multispot laser (Quantel Medical, 577 nm), Navilas laser (OD-OS, 577 nm), PRP165 contact lens, Optos Ultra-WideField Color Image system.
4：Experimental Procedures and Operational Workflow:
PRP was performed on one eye with the conventional laser and on the fellow eye with the Navilas laser. Duration and pain were recorded.
5：Data Analysis Methods:
Statistical analysis included paired two-tailed t test for pain perception and Wilcoxon test for treatment duration differences.
