“…Salgado et al 9 reported a reduction in spherical equivalent from C0.39 D before the adjustments to À0.07 D 6 months after the adjustments. A more recent study of 21 eyes by Hengerer et al 10 showed positive results at 1 year postoperatively: 96% of eyes were within G0.50 D of the intended refraction and 81% were within G0.25 D. Winkler von Mohrenfels et al 11 showed that such refractive accuracy converts to good visual outcomes, reporting a mean UDVA of 1.02 in eyes that had a light-adjustable IOL.…”

The case illustrates the use of a light-adjustable intraocular lens (IOL) in a patient who had had refractive surgery and developed blunt trauma with resultant flap damage and traumatic cataract. Consistent with early reports of the light adjustable IOL, which show positive results in non-LASIK eyes, this case suggests that the light-adjustable IOL may have similar benefits in the post-LASIK eye and other complex situations.

“…Lens-based procedures, such as in situ fine-tuning of light-adjustable IOLs, piggyback IOLs, supplementary IOLs, and IOL exchange can be used to correct large refractive errors where excimer lasers are not available [ 3 ]. In situ fine-tuning of light-adjustable IOLs is non-invasive, can be personalized to patient requirements and preferences, can adjust up to 2.0 D of sphere and cylinder in one procedure, and it is performed after complete healing has taken place and the IOL is locked in position (which increases refractive stability over time) [ 1 , 95 , 96 ]. This method has several disadvantages, some of which may result in additional visits to the ophthalmologist’s office (such as potential risk of macular burn due to ultraviolet light-based technology, requirement of pupil dilation of at least 6.5 mm, and repeat adjustments, which can also lead to dilation fatigue); in addition, it can only be performed on specific light-adjustable IOLs [ 95 , 97 ].…”

A post-operative manifest refractive error as close as possible to target is key when performing cataract surgery with intraocular lens (IOL) implantation, given that residual astigmatism and refractive errors negatively impact patients’ vision and satisfaction. This review explores refractive outcomes prior to modern biometry; advances in biometry and its impact on patients’ vision and refractive outcomes after cataract surgery; key factors that affect prediction accuracy; and residual refractive errors and the impact on visual outcomes. There are numerous pre-, intra-, and post-operative factors that can influence refractive outcomes after cataract surgery, leaving surgeons with a small “error budget” (i.e., the source and sum of all influencing factors). To mitigate these factors, precise measurement and correct application of ocular biometric data are required. With advances in optical biometry, prediction of patient post-operative refractory status has become more accurate, leading to an increased proportion of patients achieving their target refraction. Alongside improvements in biometry, advancements in microsurgical techniques, new IOL technologies, and enhancements to IOL power calculations have also positively impacted patients’ refractory status after cataract surgery.

“…Recently, a two-component silicone IOL was designed, in which power can be adjusted after implantation through UV exposure. The light-adjustable lens is entering clinical practice, and the ability to correct for spherical and cylindrical errors might overcome the 3.2 mm incision disadvantages [7,8].…”

Several intraocular lens (IOL) materials and types are currently available. Polymethyl methacrylate IOLs used to be the gold standard, but the inability of folding limits their use to selected countries and patients. Silicone IOLs were used more in the past because they are less suitable for microincisions. Foldable hydrophobic acrylic is the most popular material, which is also available in yellow (blue light absorbing) models and several IOL shapes. Although a very effective and safe material, water penetration producing glistenings and some dysphotopsia has been reported with some IOL types. Foldable hydrophilic material is widely employed in Europe, and especially for microincision cataract surgery lenses because of its plasticity, even if rare optics opacification and higher posterior capsular opacification rates have been reported in the past. Single-piece IOLs are the most employed in modern cataract surgery, but 3-piece IOLs are preferred for sulcus implantation and in infants. The aspheric design to correct or to control spherical aberration in implanted eyes is now the rule after the problems of centration we had before the capsulorhexis era were solved. However, the optical quality of pseudophakic eyes will depend not only on aberration control, but also on good media transparency and low light scattering.
