Initial Clinical Outcome With Image-Guided System for Standardized Surgical Planning in Patients Implanted With Toric IOL
Purpose
To evaluate the residual refractive cylinder, accuracy to target and refractive outcomes when using a new image guided system for surgical planning of patients implanted with a single piece hydrophobic, acrylic Toric intraocular lens (IOL) at 3 months postop.
Methods
Open label, prospective, non randomized, multi center study in 102 eyes using a new image guided system (Verion) for standard surgical planning. All patients had cataract removal using phacoemulsification and implanted with a single piece hydrophobic Toric IOL (AcrySof® Toric IOL). Residual refractive cylinder, postoperative manifest refractive spherical equivalent (MRSE) accuracy to target and uncorrected visual acuity (UCVA) were recorded at 3 months postoperatively.
Results
72% and 90.2% had residual refractive cylinder of ≤0.50D and ≤0.75D at 3 months postop follow-up respectively (p<.0001).Mean residual refractive cylinder was 0.45D (SD±0.45). 70% had postoperative MRSE accuracy to target of ≤0.50D and 87% were within ≤0.75D accuracy (p <.0001) at 3 months postop follow-up. Mean MRSE accuracy to target at 0.07D (SD±0.5).
Conclusion
The result of this study indicates low residual refractive cylinder, good accuracy to target and refractive outcomes when using the image guided system for surgical planning on patients with Toric IOL.
