“…So far, there are few studies reporting the visual outcomes of trifocal IOL implantation after previous corneal refractive surgery. Wang et al recently reported on a trifocal IOL implantation in eyes with nuclear cataract about 15 years after myopic LASIK surgery, which restored vision efficiently [ 19 ]. Chow and co-worker thereafter reported a case series of trifocal IOL implantation for post-myopic LASIK patients providing a good visual outcome at both near and distance vision [ 20 ].…”

Background: With the difficulties in IOL power calculation and the potential side effects occurring postoperatively, multifocal IOL implantation after previous corneal refractive surgery are rarely reported especially for the trifocal IOL. Herein we report the clinical observation of trifocal IOL implantation in patients with previous myopia excimer laser correction. In this study, a multi-formula average method was performed for the IOLs power calculation to improve the accuracy. Visual and refractive outcomes were analyzed, and the subjective quality of patients' life was evaluated by questionnaires survey. Methods: This retrospective case series included patients with previous myopia excimer laser correction who underwent femtosecond laser assisted phacoemulsification and trifocal IOL (AT LISA tri 839 MP) implantation. Follow-up was done at 1-day, 1-month and 3-month to assess the visual outcomes. Outcome measures were uncorrected distance, intermediate and near visual acuity (UDVA, UIVA, UNVA), manifest refraction, defocus curve, and subjective quality of vision. Results: Twenty-one Eyes from sixteen patients (14 eyes with previous laser in situ keratomileusis and 7 eyes with previous photorefractive keratectomy) were included. Mean postoperative spherical equivalent (SE) at 3-month was − 0.56 D ± 0.49 SD, wherein, 10 eyes (47.6%) were within ±0.50 D of the desired emmetropia and 19 eyes (90.5%) were within ± 1.0 D. Mean monocular UDVA, UIVA and UNVA (logMAR) at last visit were 0.02 ± 0.07, 0.10 ± 0.10, and 0.15 ± 0.11 respectively. Three patients (19%) reported halos and glare in postoperative 3 months, two of them needed to use spectacles to improve the intermediate visual acuity. Fifteen patients (94%) reported a satisfaction score of ≥3.5 out of 4.0, without any difficulty in daily activity. Thirteen patients (81%) did not need spectacles at all distances, while the other 3 patients (19%) used spectacles for near-distance related visual activity. Mean composite score of the VF-14 questionnaire was 95.00 ± 7.29 out of 100. Conclusions: Trifocal IOL implantation after myopia excimer laser correction could restore good distance, intermediate visual acuity and acceptable near visual acuity, and provide accurate refractive outcomes as well as high spectacles independence rate.

“…It has been shown to provide good outcomes of visual acuity at a near, intermediate, and far distance and a high postoperative satisfaction [16,17]. Moreover, two previous studies also demonstrated that it can provide a good visual outcome at both near and distance vision for post-myopic LASIK cases [18,19].…”

During phacoemulsification for cataracts, the surgeon may encounter various challenges and should therefore be trained to handle them. This chapter will share an example of clinical cases encountered by the author in clinical practice, which mainly includes the successful implantation of a trifocal intraocular lens in the capsular bag after posterior capsular tear during posterior polar cataract surgery as well as cataract surgery design after corneal refractive surgery, shrinkage, and treatment of capsular opening in patients with retinitis pigmentosa after cataract surgery to provide a reference for clinicians.

Cataract is the leading cause of blindness worldwide, and advanced cataract techniques such as femtosecond laser-assisted cataract surgery (FLACS) have been commercially available. Corneal refractive surgery (CRS) is one of the most popular surgeries for the correction of refractive errors. CRS changes the cornea not only anatomically but also pathophysiologically. However, there has been no clinical research analyzing the refractive and safety outcomes of FLACS after CRS. The aim of this study is to evaluate whether FLACS after CRS is more effective and safe than conventional PCS. Participants with a previous CRS history who underwent FLACS or conventional PCS were included in this study. The visual outcomes and the refractive outcomes including refractive, corneal, and ocular residual astigmatism were compared. The safety outcomes were then studied intraoperatively and postoperatively. A total of 102 patients with age-related cataract were enrolled. At 3 months postoperatively, UCVA, BCVA, and predictive error were not significantly different between the FLACS and conventional PCS groups. Reduction of refractive astigmatism was higher in FLACS. Postoperative ORA was significant lower in FLACS. Reduction of ORA was higher in FLACS. The intraoperative and postoperative complications were also not significantly different between the two groups. FLACS was found to be effective in patients with a previous history of CRS in terms of vision and refractive outcomes and was free from adverse effects. The competitive edge of FLACS in postoperative ORA, with the reduction of refractive astigmatism and ORA, may provide better visual quality than conventional PCS.
