Refractive Outcomes of Phacovitrectomy in Retinal Detachment Compared to Phacoemulsification Alone Using Swept-Source...

Area of Science:

• Ophthalmology
• Biomedical Optics
• Retinal Surgery

Background:

• Assessing refractive outcomes after cataract surgery is crucial for patient satisfaction.
• Combined phacovitrectomy for retinal detachment presents unique challenges for refractive prediction.
• Advancements in biometry, such as swept-source optical-coherence-tomography (SS-OCT), aim to improve refractive accuracy.

Purpose of the Study:

• To compare refractive outcomes between combined phacovitrectomy and phacoemulsification using SS-OCT biometry.
• To determine if an adjustment factor is necessary for intraocular lens (IOL) selection in these procedures.
• To evaluate the accuracy of SS-OCT biometry in predicting refractive outcomes.

Main Methods:

• Retrospective study of 95 eyes (52 phacovitrectomy, 43 phacoemulsification).
• Utilized SS-OCT biometry for measurements.
• Analyzed mean refractive error (ME) and mean absolute error (MAE) for comparison.

Main Results:

• No statistically significant difference in postoperative refractive shift between the two groups.
• ME: 0.05 D (phacovitrectomy) vs. 0.03 D (phacoemulsification).
• MAE showed no significant difference, indicating high refractive predictability.

Conclusions:

• SS-OCT biometry provides superior refractive outcomes compared to previous methods.
• No adjustment factor is recommended for IOL selection when using SS-OCT.
• The technology enhances refractive predictability in complex cataract surgeries.
