Presbyopia management with Q-factor modulation without additive monovision: One-year visual and refractive results

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Presbyopia correction remains a challenge, particularly for hyperopic patients intolerant to monovision.
• Q-factor modulation offers a potential alternative to traditional presbyopia treatments.

Purpose of the Study:

• To evaluate refractive outcomes of Q-factor modulation for hyperopic presbyopia correction without induced monovision.
• To assess visual acuity and patient satisfaction after this novel surgical approach.

Main Methods:

• A prospective study included 45 hyperopic presbyopic patients unsuitable for monovision.
• Surgical targets included emmetropia in the dominant eye and emmetropia with a Q-factor of -0.8 in the nondominant eye.
• Postoperative assessments included visual acuity (distance and near), refractive error, and patient satisfaction at 12 months.

Main Results:

• 93% achieved 20/20 binocular uncorrected distance visual acuity (UDVA), and 82% achieved Jaeger 2 near visual acuity (UNVA).
• Mean spherical equivalent (SE) shifted to -0.22 D in dominant eyes and -0.83 D in nondominant eyes (P < .0001).
• 87% of patients reported satisfaction and willingness to recommend the procedure.

Conclusions:

• Q-factor modulation without monovision effectively addresses hyperopic presbyopia by enhancing depth of field.
• The procedure yields satisfactory visual outcomes and high patient satisfaction.
• This technique presents a promising alternative for presbyopia correction in specific patient populations.
