A digital light delivery device (DLD) is used to adjust LAL power in situ to correct residual refractive errors non-invasively. Profiles developed to correct residual cylindrical and spherical errors were tested on five patients, with postoperative toric refractive errors of 1.25–1.75 D. At 2 weeks post-implantation, best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA) and residual refractive errors were measured.Results Toric error was reduced in each of the patients and refractions remained stable for the 9 month follow-up period. Achieved spherical equivalent manifest refraction (MRSE) was within 0.25 D of targeted emmetropia. All five patients improved their UCVA to ≥20/25 (≤0.1 logarithm of the minimum angle of resolution (LogMAR)) and maintained their BCVA.Conclusion The LAL can be adjusted postoperatively to correct residual astigmatism. %U https://bjo.bmj.com/content/bjophthalmol/94/6/690.full.pdf
