Abstract: PURPOSE To evaluate the efficacy, predictability, and safety of three different procedures (intraocular lens [IOL] exchange, piggyback lens implantation, and LASIK) to correct residual refractive error following cataract surgery. METHODS A retrospective multicenter study comprised 65 eyes of 54 patients that underwent phacoemulsification, resulting in a unacceptable final refractive error. Eyes were divided into three groups: eyes that had an IOL lens exchange (17 eyes), eyes that had a piggyback lens implanted (20 eyes), and eyes that had LASIK (28 eyes). RESULTS No differences between the IOL exchange and piggyback lens groups in the spherical equivalent, sphere, or cylinder were found (P = .072, .436, and .081, respectively). The LASIK group showed a statistically significant reduction in spherical equivalent and refractive cylinder when compared with the IOL exchange group (P < .001 and P = .001, respectively). The LASIK group showed statistically significant reduced refractive cylinder in comparison with the piggyback lens group (P = .002). The median efficacy index was 0.58 (range: 0.28 to 0.93), 0.75 (range: 0.65 to 0.92), and 0.91 (range: 0.85 to 1.14) in the IOL exchange, piggyback lens, and LASIK groups, respectively. Statistically significant differences were found between the IOL exchange and LASIK groups (P = .004) and the piggyback lens and LASIK groups (P = .003). No statistically significant differences were detected in the safety index among groups (P = .094). The predictability (±1 diopters of final spherical equivalent) was 62.5% of eyes in the IOL exchange group, 85% of eyes in the piggyback lens group, and 100% of eyes in the LASIK group. CONCLUSIONS The three procedures were effective. The LASIK group showed the best outcomes in efficacy and predictability.

Multifocal Intraocular Lenses: An Overview
Jorge L. Alió,Ana B. Plaza-Puche,Roberto Fernández-Buenaga,Joseph Pikkel,Miguel J. Maldonado +4 more
TL;DR: To avoid patient dissatisfaction after multifocal intraocular lens implantation, it is important to consider preoperatively the patient's lifestyle; perform an exhaustive examination including biometry, topography, and pupil reactivity; and explain the visual expectations and possible postoperative complications.

Optimizing outcomes with toric intraocular lenses
TL;DR: Conventional manual marking has given way to image-guided systems and intraoperative aberrometry, which provide a mark-less IOL alignment and also aid in planning the incisions, capsulorhexis size, and optimal IOL centration.

Managing residual refractive error after cataract surgery
TL;DR: The light-adjustable IOL may provide an ideal treatment to pseudophakic ametropia by obviating the need for secondary invasive procedures after cataract surgery, but it is not widely available nor has it been sufficiently studied.

Management of residual refractive error after cataract surgery
TL;DR: It was found that Piggyback IOL were safer and more accurate than IOL exchange and LASIK seems to be the most accurate method for its correction.

Aiming for emmetropia after cataract surgery : Swedish National Cataract Register study
TL;DR: Emmetropia is the goal in most cataract cases but was reached in only 55% of eyes planned for emmetropia, and remaining corneal astigmatism and biometry prediction errors in astigmatic and ametropic eyes were high.

Effects of intraocular lens position errors on postoperative refractive error
TL;DR: The effects of misalignment are shown to influence the spherical refractive component primarily and are likely that longitudinal IOL positional errors are a principal component of postoperative refractive errors.

TL;DR: Eximer laser PRK is effective in reducing residual myopia after previous refractive and cataract surgery, however, it is less accurate than PRK in eyes that did not undergo surgery and is more likely to cause a loss of best-corrected visual acuity 1 year after treatment.

Secondary procedures after presbyopic lens exchange.
TL;DR: Photorefractive keratectomy enhancement can improve distance vision but has a limited effect on halos, and presbyopic lens exchange in eyes with emmetropia and low hyperopia was associated with a significantly higher percentage of secondary procedures.

Excimer laser surgery for correction of ametropia after cataract surgery.
TL;DR: Laser refractive surgery was a safe, effective, and predictable method to correct ametropia after cataract extraction with intraocular lens (IOL) implantation and best spectacle‐corrected visual acuity remained unchanged or improved in every case.
