Narrative Responses:

Purpose
Current multifocal intraocular lenses often have unwanted visual phenomenon such as glare and halo. The purpose of this study is to evaluate the visual outcomes, postoperative visual symptoms, and complications of two new bifocal intraocular lenses (SBL-3, Lenstec, St. Petersburg, FL; Lentis Mplus, Oculentis, Berlin, Germany).

Methods
The study is a retrospective chart review of 10 patients (20 eyes) who underwent bilateral bifocal intraocular lens implantations. The main outcome measures include uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), best-corrected distance visual acuity (BCDVA) and distance-corrected near visual acuity (DCNVA). Other outcomes including patients’ subjective experience of glare and halo, as well as complications, were examined.

Results
At 1 month, the UDVA was significantly improved from 0.30 logMAR preoperatively to 0.00 logMAR postoperatively (P<0.03). Furthermore, there was an improvement in BCDVA from 0.10 logMAR preoperatively to 0.00 logMAR postoperatively, although these results were not statistically significant (P<0.25). The postoperative UNVA was 0.048 logMAR. No complications were reported.

Conclusion
This study showed that both bifocal intraocular lenses are effective in improving both distance and near visual acuities. Both implants are safe and no complications were observed.
