“…Cataract surgery is a safe procedure with the best refractive outcomes through advances in intraocular lens (IOL) technology and phacoemulsification techniques. Although accurate biometry and IOL power calculation are possible, refractive surprise may occur postoperatively (1)(2)(3). Piggybacking a secondary IOL can be used to correct pseudophakic refractive errors.…”

“…Visual recovery who underwent cataract surgery is closely related to the use of appropriate IOL power calculation. [6][7][8] LRIs have been used to correct preexisting astigmatism during the time of cataract surgery. Simultaneously, one can benefit from low costs and easy performance with minimal learning curve, without overcorrection.…”

“…The most frequent postoperative problem is a residual refractive error, which may lead to suboptimal visual outcomes and patient's dissatisfactions since patients generally consider spectacle-free as an important issue. [ 3 4 21 22 23 24 ] Causes of residual refractive error include errors in biometry measurement and the use of inappropriate power calculation formulas, as well as IOL manufacturing inaccuracies, displacement of the IOL in the capsular bag, the excessive rotational divergence of a toric IOL, and other reasons. [ 3 6 7 25 26 27 28 ] For successful outcome with premium IOLs, accurate correction of even small spherical and cylindrical errors is necessary, especially for those with diffractive multifocal IOL implantation.…”

PURPOSE:The aim of this study is to evaluate the effectiveness and predictability of photorefractive keratectomy (PRK) for correcting residual refractive error following cataract surgery with premium intraocular lens (IOL) implantation.METHODS:We conducted a retrospective review of the medical records of patients who received PRK for correcting residual hyperopia, myopia, and/or astigmatism due to unsatisfied uncorrected distance visual acuity (UDVA) after cataract extraction with implantation of aspheric, diffractive multifocal, or toric IOL from September 2011 to December 2017. Pre-cataract surgery, pre- and post-PRK data including UDVA, best-corrected distance visual acuity, and refractive status were analyzed.RESULTS:A total of 18 consecutive eyes in 17 patients were included in this study. The UDVA after PRK improved 1 line or more in 10 eyes, remained unchanged in five eyes, and decreased in three eyes. The overall improvement in the logarithm of minimal angle of resolution (logMAR) UDVA after PRK was significant (P < 0.05). While dividing patients into subgroups based on IOL type, significant improvement in logMAR UDVA was found in patients with aspheric IOL or diffractive multifocal IOL implantation (P < 0.05). No significant improvement of UDVA was found in patients with toric IOL implantation. All eyes achieved ± 1.00 D of the attempted spherical correction, demonstrating good predictability of PRK.CONCLUSIONS:PRK was a safe and effective procedure to correct residual refractive error following cataract extraction with premium IOL implantation. Although satisfactory for all patients, the outcome is better and more predictable in patients with aspheric and diffractive multifocal IOL implantation and is less satisfactory and unpredictable in patients with toric IOL implantation.
