Abstract
PURPOSE To evaluate the effectiveness, safety, and stability of a modified PRESBYOND Laser Blended Vision protocol (Carl Zeiss Meditec AG) for correcting hyperopic astigmatism and presbyopia, using Custom Refractive Software Master (CRSM) targeting over a 6-month period. METHODS A total of 636 eyes of 318 patients with a mean age of 51.05 ± 4.71 years (range: 40 to 60 years) met the inclusion and exclusion criteria. All patients completed a 6-month follow-up. CRSM software was used to generate ablation profiles for the MEL90 excimer laser (Carl Zeiss Meditec AG). The target refraction was emmetropic for the dominant eyes and between -0.75 and -1.12 diopters (D) for the near eyes. RESULTS Visual and refractive results were studied separately by the dominant and non-dominant eyes. The mean attempt to correct for spherical equivalent refraction was +2.17 ± 1.16 D (range: -1.00 to +5.37 D). The mean attempted cylinder was -0.60 ± 0.75 D (range: -4.00 to 0.00 D). All eyes monocularly achieved uncorrected distance visual acuity (UDVA) of 20/25 or better after refractive treatment and 88% achieved 20/20. Binocularly all eyes achieved UDVA of 20/25 or better and 96.54% achieved 20/20. Ninety-eight percent of the patients maintained their corrected distance visual acuity before surgery and UDVA 6 months after surgery. CONCLUSIONS This hyperopic micro-anisometropia protocol with PRESBYOND Laser Blended Vision was an effective, safe, and well-tolerated refractive treatment. It was an effective procedure with excellent results for UDVA and uncorrected near visual acuity and demonstrates that binocular summation exists. [ J Refract Surg. 2024;40(7):e480-e489.].

J Clin Med 2024; 13:3011. [PMID: 38792550 PMCID: PMC11122580 DOI: 10.3390/jcm13103011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 05/13/2024] [Accepted: 05/16/2024] [Indexed: 05/26/2024] Open
Abstract
Background/Objectives: Presbyopia, a common age-related refractive error, affects over a billion people globally and significantly impacts daily life. Methods: This retrospective study analyzed 288 eyes of 144 patients undergoing LBV PRESBYOND® treatment for myopic presbyopia with astigmatism, aiming to evaluate precision, efficacy, safety, and stability over six months. Results: Key findings include high efficacy, with 99% of distance-eyes achieving uncorrected distance visual acuity (UDVA) of 20/25 or better, and 85% of near-eyes achieving UDVA of 20/32 or better. The results show excellent refractive outcomes, with 99% of long-sighted eyes and 97% of near-sighted eyes having a postoperative spherical equivalent within ±1.00 D. Safety was demonstrated by no loss of two or more Snellen lines after treatment, with 94% of patients maintaining corrected distance visual acuity (CDVA) before and after surgery. Conclusions: Overall, LBV PRESBYOND® proved effective, safe, and well tolerated for myopic presbyopia correction, offering satisfactory visual outcomes and potential spectacle independence for various distances. This study underscores the importance of individualized treatment based on patient age, highlighting the positive impact of binocular summation on visual function. This study contributes to the growing body of evidence supporting LBV PRESBYOND® as a viable option for addressing presbyopic myopia, offering insights into its efficacy and safety profile. Further research could explore postoperative stereopsis and long-term outcomes to enhance understanding and refine treatment protocols.

Abstract
PURPOSE To determine the efficacy, safety, predictability, and stability of laser in situ keratomileusis (LASIK) in the treatment of presbyopia. METHODS The databases of CNKI, VIP, Wan-Fang, CBM, Chinese Clinical Registry, PubMed, The Cochrane Library, Web of Science, Embase, and ClinicalTrials.gov were searched until March 2023. The authors chose the studies of LASIK in the treatment of presbyopia. Outcomes were efficacy, safety, predictability, and stability. The review was registered in the international platform of registered systematic review and meta-analysis protocols (INPLASY202350005). RESULTS A total of 28 non-randomized controlled trials (15,861 eyes) were included. The results showed that after LASIK, (1) the distance efficacy decreased (mean difference [MD]: 0.02, 95% CI: 0.0 to 0.03, P < .05) and the near efficacy increased (MD: -0.01, 95% CI: -0.19 to-0.02, P < .05); (2) the distance safety decreased (MD: 0.07, 95% CI: 0.04 to 0.10, P < .0001) and near safety increased (MD: -0.19, 95% CI: -0.39 to 0.02, P > .05); (3) the predictability within ±1.00 and ±0.50 D was 94% (relative risk [RR]: 0.94, 95% CI: 0.90 to 0.98, P < .001) and 80% (RR: 0.80, 95% CI: 0.74 to 0.86, P < .001), respectively; and (4) 6 months postoperatively, the percentage of spherical equivalent changing within ±0.50 D was 95% (RR: 0.95, 95% CI: 0.89 to 0.99, P < .001). CONCLUSIONS The near efficacy, predictability, and stability of LASIK for presbyopia correction were satisfactory; however, the distance efficacy and distance safety decreased.

Presbyopic LASIK using the Supracor algorithm and micromonovision in presbyopic myopic patients: 12-month visual and refractive outcomes. J Cataract Refract Surg 2023; 49:195-200. [PMID: 36325836 DOI: 10.1097/j.jcrs.0000000000001080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 10/10/2022] [Indexed: 11/06/2022]
Abstract
PURPOSE To evaluate the visual and refractive outcomes for presbyopia and myopia treatment using the Teneo 317 M2 platform and the myopic Supracor algorithm. SETTING Percy Military Hospital and Private Laser Victor Hugo Center, Paris, France. DESIGN Observational retrospective nonrandomized study. METHODS 50 eyes (25 patients) treated with bilateral myopic Supracor and micromonovision using the Teneo 317 M2 platform and followed up for 12 months. Study outcomes included binocular and monocular visual acuities (without correction for distance and near vision), the spherical equivalent, predictability, stability, safety, optical aberrations, and complications. RESULTS The mean age was 50.6 ± 2.7 years, and the mean preoperative spherical equivalent was -2.6 ± 1.4 diopters. At 12 months postoperatively, the mean binocular uncorrected distance visual acuity was 0.02 ± 0.03 logMAR, and 24 patients (96%) achieved an acuity of 20/25 or better. The binocular uncorrected near visual acuity was equal to Jaeger 1 in 18 patients (72%) and Jaeger 2 or better in 23 patients (92%). 12 eyes (24%) had lost 1 Snellen line, and 1 eye (2%) had lost 2 Snellen lines of monocular corrected distance visual acuity. No cases required retreatment; however, 1 eye (2%) underwent revision surgery because of diffuse lamellar keratitis. CONCLUSIONS This study suggests that Supracor using the Teneo 317 M2 platform is a safe and effective technique for myopia and presbyopia treatment. Supracor is therefore a viable alternative to monovision for presbyopia and myopia. However, a careful patient selection is essential to satisfy realistic expectations.

Abstract
Presbyopia can be defined as the refractive state of the eye in which, due to a physiological decrease in the ability to accommodate, it is not possible to sustain vision without fatigue in a prolonged manner, along with difficulty focusing near vision. It is estimated that its prevalence in 2030 will be approximately 2.1 billion people. Corneal inlays are an alternative in the correction of presbyopia. They are implanted beneath a laser-assisted in situ keratomileusis (LASIK) flap or in a pocket in the center of the cornea of the non-dominant eye. The purpose of this review is to provide information about intraoperative and postoperative KAMRA inlay complications in the available scientific literature. A search was conducted on PubMed, Web of Science, and Scopus with the following search strategy: ("KAMRA inlay" OR "KAMRA" OR "corneal inlay pinhole" OR "pinhole effect intracorneal" OR "SAICI" OR "small aperture intracorneal inlay") AND ("complication" OR "explantation" OR "explanted" OR "retired"). The bibliography consulted shows that the insertion of a KAMRA inlay is an effective procedure that improves near vision with a slight decrease in distance vision. However, postoperative complications such as corneal fibrosis, epithelial iron deposits, and stromal haze are described.

Abstract
PURPOSE To review all case series of refractive corneal inlay implantation: Flexivue (Presbia, Netherlands), Invue (BioVision, Brügg, Switzerland) and Icolens (Neoptics, Hünenberg, Switzerland) performed in presbyopia patients and to evaluate the reported visual outcomes. In addition, our aim is to provide assessment for complications and to report the satisfaction rates. METHODS PubMed, Web of Science and Scopus databases were consulted using "refractive corneal inlay", "Flexivue Inlay", "Invue Inlay" and "Icolens inlay" as keywords. 147 articles were found, and they were assessed considering the inclusion and exclusion criteria. After filtering, this systemic review included ten articles, published between 2011 and 2020. RESULTS 308 eyes from 308 participants were enrolled in this systematic review. Mean maximum follow-up was 13.9 months. Nine of the ten case series included used femtosecond laser for the corneal pocket creation. Mean pocket depth was 293.75 µm. 77.5% of the eyes reported a postoperative uncorrected near visual acuity of 20/32 or better, and 19.20% of the inlay-implanted eyes achieved an uncorrected distance visual acuity of 20/20 or better. The most prominent complications were halos, pain, photophobia, and poor distance visual acuity. 27 eyes (8.7%) had to be explanted due to complications, such as near-distance spectacle dependence or blurred distance vision. CONCLUSION Refractive corneal inlay outcomes demonstrated high efficacy, safety, and satisfaction rates. Furthermore, it is a reversible technique. However, the findings must be viewed with caution due potential conflict of interest. Further research with higher sample size is needed to validate these findings.

Abstract
PURPOSE To compare the visual outcome and refractive results between presbyopic photorefractive keratectomy (presbyPRK) and presbyopic laser in situ keratomileusis (presbyLASIK) in presbyopic hyperopic patients using micromonovision and the SUPRACOR algorithm. SETTING Percy Military Hospital and private Laser Victor Hugo Center, France. DESIGN Observational retrospective nonrandomized. METHODS Twenty-three patients who had undergone presbyPRK or presbyLASIK were included and followed up for 12-months. Far and near visual acuity without correction in monocular and binocular, measurement of distance visual acuity with correction in monocular, evaluation of spherical equivalent (SE), aberrometry, and patient satisfaction were measured and analyzed in this study. RESULTS The study included 26 eyes of 13 patients in the presbyLASIK group and 20 eyes of 10 patients in the presbyPRK group. The mean age was 55.43 ± 4.6 years. Uncorrected binocular distance visual acuity was 0.030 ± 0.05 logMAR in the presbyLASIK group and 0 logMAR in the presbyPRK group (P = .066). Binocular near visual acuity without correction was 0.21 ± 0.11 logMAR in the presbyLASIK group and 0.30 ± 0.15 logMAR in the presbyPRK group (P = .0398). For the dominant eyes, the SE was -0.08 ± 0.48 diopters (D) in the presbyLASIK group and 0.16 ± 0.82 D in the presbyPRK group (P = .3995). For nondominant eyes, the SE was -0.44 ± 0.50 D in the presbyLASIK group and 0.12 ± 0.65 D in the presbyPRK group (P = .0254). CONCLUSIONS PresbyPRK and presbyLASIK were comparable in efficacy, stability, predictability, and safety. PresbyPRK could be a safe and effective surgical alternative for the hyperopic presbyopic patient.

Abstract
PresbyLASIK is one of the most commonly used modalities of surgical correction in presbyopes with no cataract. Unlike monovision procedures, both the eyes are adjusted for near and distance, providing a good stereopsis. This works by creating a corneal multifocality and increasing the depth of focus. Most techniques of presbyLASIK currently employ hybrid methods, i.e., a component of monovision added on to a multifocal corneal ablation. Choosing an appropriate proportion of these two components according to the patients' requirements and meticulous patient selection are key to obtaining desirable outcomes. Being corneal-based procedures, presbyLASIK has shown to be reversible. Thorough updated knowledge of the different presbyLASIK procedures, their principles and outcomes based on previous studies is required before a refractive surgeon plans to start providing presbyLASIK services. We performed a comprehensive search on PubMed with the keywords "Presbyopia surgery," "PresbyLASIK" "PresbyMAX," "Supracor," and "Custom-Q." In this review article, we have explained the principles of the various presbyLASIK procedures, appropriate patient selection and planning on the devices with examples, and summarized the previously published outcomes of these techniques.
