Research background

Diabetic cataract is a common complication among diabetic patients, characterized by altered ocular physiology. Traditional cataract surgery methods have limitations in addressing the unique challenges posed by the diabetic eye. The integration of femtosecond laser-assisted phacoemulsification with Toric intraocular lens (IOL) implantation presents a novel approach in the treatment of diabetic cataracts.

Research motivation

This study was motivated by the need to improve surgical outcomes in diabetic cataract patients. The specific focus was on evaluating whether the advanced technique of femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation could offer better results compared to traditional methods, particularly in terms of postoperative vision and complication rates.

Research objectives

The primary objective was to assess the clinical efficacy and potential complications of femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation in diabetic cataract patients. The study aimed to compare this method with traditional phacoemulsification techniques.

Research methods

A retrospective study design was employed, involving 120 diabetic cataract patients from May 2019 to May 2021. They were randomly divided into a control group (traditional phacoemulsification with Toric IOL) and a treatment group (Len Sx femtosecond laser-assisted surgery). Key metrics for evaluation included naked eye vision, astigmatism levels, high-level ocular phase difference detection, clinical efficacy, and analysis of complications.

Research results

The study found no significant preoperative differences between the two groups in terms of astigmatism and naked eye vision. However, postoperatively, the treatment group showed more significant improvements in both naked eye vision and astigmatism at the six-month follow-up. High-level corneal phase difference tests also indicated better outcomes for the treatment group.

Research conclusions

Femtosecond laser-assisted phacoemulsification combined with Toric IOL implantation is more effective in improving postoperative visual outcomes in diabetic cataract patients than traditional phacoemulsification. This method could represent a significant advancement in the surgical treatment of diabetic cataracts.

Research perspectives

This study opens up new perspectives for the treatment of diabetic cataracts. Future research should focus on further refining femtosecond laser-assisted techniques, exploring long-term outcomes, and broadening the scope to include diverse patient populations. Additionally, further studies could delve into the underlying mechanisms of improved outcomes with this method.
