Purpose

To evaluate the accuracy and efficiency of a digital integrated manifest refraction system compared with standard manifest refraction in pseudophakic eyes.

Setting

From Anterior Segment Service CODET Vision Institute, Tijuana, Mexico and Universidad
Autónoma de Baja California, Baja California, Mexico

Methods

Prospective, double-blind study analyzed 100 eyes from 100 pseudophakic patients, 35 eyes received mono-
focal intraocular lenses (MA60AC, Alcon Labs, Inc]; MX60, Bausch & Lomb, Inc; CNA00, Alcon Labs, Inc; SN60AT, Alcon Labs, Inc) and 65 eyes received trifocal IOLs (TFNT00, Alcon Labs, Inc; ZFR00V, Johnson & Johnson Surgical Vision, Inc). All patients underwent objective refraction with the Nidek ARK-530A autorefractor, followed by manifest refraction performed with either the Topcon VT-100
(Std-MR group) or the digital integrated manifest refraction unit TS-610 (Nidek Co, Ltd) (DI-MR group). Outcomes assessed
included manifest spherical equivalent, refractive cylinder, time, correlation, and agreement between methods.

Results

The mean manifest spherical equivalent was –0.15 ± 0.38 diopters (D) with the TS-610 and –0.14 ± 0.38 D with standard refraction (P = .31). Linear regression demonstrated a strong correlation between methods (R = 0.914, R2 = 0.835, P < .001). The mean cylinder was –0.66 ± 0.52 D (TS-610) versus –0.62 ± 0.57 D (Std-MR), with a mean difference of –0.11 ± 0.17 D and a centroid of 0.01 ± 0.20 D in vector analysis. DI-MR significantly reduced testing time (3.1 ± 1.8 minutes) compared with Std-MR (7.1 ± 7.4 min-
utes, P = .001).

Conclusions

The automated TS-610 manifest refraction system demonstrated excellent agreement with Std-
MR refraction in pseudophakic eyes, while significantly reducing testing time. DI-MR provides a reliable and ef-
ficient alternative for postoperative evaluation and may enhance workflow efficiency in cataract and refractive
practices.
