Initial Clinical Outcome With Image-Guided System for Standardized Surgical Planning in Patients With Different IOL Platforms
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 aspheric monofocal intraocular lens (IOL) and multifocal IOL at 3 months postop.
Open label, prospective, non randomized, multi center study in 188 eyes using a new image guided system (Verion) for standard surgical planning. All patients had femtosecond laser (LenSx) assisted cataract removal using phacoemulsification and any pre-op astigmatism was treated with astigmatic keratotomy (AK). Group I (n=88) were implanted with a single piece aspheric IOL (SN60WF). Group 2 (n=100) were implanted with multifocal IOL (AcrySof IQ ReSTOR). Residual refractive cylinder, postoperative manifest refractive spherical equivalent (MRSE) accuracy to target and uncorrected visual acuity (UCVA) were recorded at 3 months postoperatively.
At 3 months follow-up, group I (n= 88): 62% and 83% had residual refractive cylinder of ≤0.50D and ≤0.75D and group II(n=100): 71% and 88% residual refractive cylinder of ≤0.50D and ≤0.75D respectively. Group I: 77% had MRSE of ≤0.50D and 98% were within ≤0.75D accuracy. Group II: 82% had MRSE of ≤0.50D and 94% were within ≤0.75D accuracy.
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 different IOL platforms.
