Effect of microinterventional endocapsular nucleus disassembly using centripetal loop fragmentation on refractive...

Area of Science:

• Ophthalmology
• Surgical Technology
• Refractive Surgery

Background:

• Cataract surgery involves nucleus disassembly, which can lead to lens zonulocapsular instability.
• Minimizing intraoperative complications is crucial for achieving optimal refractive outcomes post-cataract surgery.

Purpose of the Study:

• To evaluate the refractive impact of centripetal fragmentation using the miLOOP system for nucleus disassembly.
• To assess if the miLOOP system minimizes lens zonulocapsular instability during endocapsular lens manipulation.

Main Methods:

• Retrospective comparative consecutive series evaluating refractive outcomes.
• Compared patients undergoing cataract surgery before and after introducing the miLOOP system for nucleus disassembly.
• Primary outcome was median absolute error (MedAE); secondary outcomes included visual acuity and prediction error within diopter ranges.

Main Results:

• The microinterventional miLOOP technique showed a significantly lower MedAE (0.107 D) compared to conventional methods (0.191 D).
• A trend towards higher proportions of eyes achieving better corrected distance visual acuity (CDVA) and uncorrected distance visual acuity (UDVA) was observed with the miLOOP system.
• More eyes achieved refractive outcomes within ±0.25 D and ±0.50 D of the predicted refraction using the microinterventional approach.

Conclusions:

• Microinterventional nucleus disassembly using the miLOOP system may improve refractive outcomes in cataract surgery.
• This technique shows potential for reducing refractive prediction error, leading to enhanced patient results.
