Blended Vision Achieved by Combining High and Low Addition Power Diffractive Intraocular Lenses with Micromonovision: A Clinical Outcome
Purpose. To evaluate the clinical outcome of blended vision combined with micromonovision (MMBV) using a + 4 diopter (D) addition power (add) diffractive intraocular lens (MIOL) and a + 2.75 D add MIOL with a myopic target of −0.5 D. Methods. One hundred twenty eyes of 60 cases were enrolled. The +4...

| description | Purpose. To evaluate the clinical outcome of blended vision combined with micromonovision (MMBV) using a + 4 diopter (D) addition power (add) diffractive intraocular lens (MIOL) and a + 2.75 D add MIOL with a myopic target of −0.5 D. Methods. One hundred twenty eyes of 60 cases were enrolled. The +4 D add MIOLs were placed in the nondominant eye, the +2.75 D add MIOLs were placed in the dominant eye with a myopic target of −0.5 D in 30 cases (the MMBV group), and the +4 D add MIOLs were placed in both eyes in another 30 cases (controls). Postoperative clinical outcomes were compared between the two groups. Results. Compared with the controls, binocular uncorrected intermediate vision at 70 cm was significantly better in the MMBV group (p=0.02). Contrast sensitivity at 12 cycles per degree and the 6% and 12.5% low-contrast visual acuities were also significantly better in the MMBV group compared with the controls (p values = 0.05, 0.05, and 0.04, respectively). Uncorrected and corrected distance and near VA did not differ significantly between the two groups. Conclusion. MMBV provided a better intermediate VA, contrast sensitivity, and low-contrast VA than bilateral implantation of the +4 D add MIOL, while preserving comparable near and distance vision. |
