PURPOSE:

The ability of a toric contact lens to properly orient on eye and maintain orientation is important for delivering optimal visual acuity and performance. Revive Toric (hioxifilcon D) soft contact lenses are engineered with a toric posterior surface specifically designed to correct astigmatism. In addition, Revive Toric lenses incorporate a specialized thin orientation zone, ensuring the lens remains correctly aligned throughout wear. This precise design is intended to enhance rotational stability, thereby providing visual performance and patient satisfaction for individuals with astigmatic refractive errors. The purpose of this study was to evaluate the visual performance and on-eye stability of Revive Toric contact lenses.

METHODS:

In this post-market, bilateral, repeated-measures study, experienced toric contact lens wearers were enrolled. At the screening/baseline visit, participants underwent baseline sphero-cylindrical refraction, high-contrast, high-illumination logMAR visual acuity, visual quality and corneal topography. Custom toric lenses were ordered according to the Revive Toric fitting guide. Eligible participants returned and lenses were dispensed. After a 10-minute settling period, visual acuity and lens fit (including centration and orientation) were evaluated. If vision and fit were acceptable, participants wore lenses for 8-16 hours per day for approximately 1 week. At the 1-week follow-up, visual acuity and lens fit parameters were re-assessed including rotational recovery (measured 60 seconds after manually rotating the lens to 45° temporal). Data was collected using standardized procedures and scales.

RESULTS:

32 participants were enrolled and 26 (12 female and 14 male; mean age 43.6 years) completed the study. Visual acuity and visual quality showed no statistically significant differences between baseline spectacle correction and contact lens-correction at both the dispensing and follow-up visits (p≥0.126 in all cases). Lens evaluations revealed consistent performance, with acceptable centration, lens movement, lens surface, and negligible oscillation with blink. At the dispensing visit, 69% of the lenses were oriented within 10° of the expected position, which improved to 85% at the 1-week follow-up. Moreover, 75% of the lenses demonstrated rotational recovery within 10° after 60 seconds.

CONCLUSION:

Revive Toric soft contact lenses delivered consistent visual acuity; outcomes were equivalent to baseline spectacle correction. Excellent lens fit and rotational stability were maintained over 1 week of daily wear.
