“…Clinical outcomes using different techniques of presbyopic LASIK were reported and summarized in several recent studies. 3,5,29,30 The current development throughout the corneal surgical compensation for presbyopia in hyperopic patients indicates a converging trend toward hybrid techniques. Strategies involve a combination of different optical principles, including monovision, multifocality, asphericity modification, and pinhole, to improve visual outcomes.…”

“…Different authors such as Mosquera and Alió, Pallikaris and Panagopoulou and Alió et al have concluded that rigorous objective studies with adequately long follow‐up periods are necessary to better qualify the different presbyLASIK techniques. Most studies have only followed up patients for one year or less . The longest follow‐up reported by Epstein et al was 2.5 years, in a study concerning a peripheral presbyLASIK technique.…”

“…The outcomes of presbyLASIK are affected by the progressive decay in accommodation that occurs with ageing, and criticisms have been raised about this type of LASIK surgery, as limited evidence has been reported in this regard . The subtle changes induced in the anterior corneal surface by the so‐called presbyLASIK techniques may be prone to regress due to epithelial compensation .…”

Background: There is a lack of scientific evidence on long-term follow-up of the outcomes of the presbyLASIK techniques. This study aimed to objectively evaluate corneal stability three years following excimer laser central presbyLASIK.Methods: This is a longitudinal, retrospective, observation of a consecutive series of cases comprising 24 eyes which had been treated by central myopic or hyperopic Presbymax central presbyLASIK. Eyes treated with the same version of presbyLASIK software were included and followed by corneal topography at three months, one and three years after surgery. Based on the corneal topography data, customised softwarebased on a light propagation algorithm and developed using Matlab softwarewas used to analyse the simulated behaviour of light through the ocular media. The range of objective corneal depth of focus was also measured. Results: Results were assessed separately for myopes and hyperopes at pupillary diameters of 3.0 and 6.0 mm. The results showed corneal multifocality outcomes to remain constant (p > 0.05) throughout the three-year follow-up period. Conclusion: The use of light propagation analysis of the multifocal anterior corneal surface following a Presbymax central presbyLASIK procedure demonstrated stable outcomes over a three-year follow-up period.

“…Laser-assisted corrections [20–23], intrastromal rings [24], corneal inlays [25, 26] and lenticular approaches [27–29] attempt to address the presbyopia-related productivity loss and variable optical outcomes and satisfaction rates have been reported. Despite the variance of the published data, it is widely accepted that lenticular approaches offer an almost permanent surgical outcome for presbyopia since they address the ongoing or upcoming cataract changes of the lens as well, which are common in middle-aged and elderly presbyopes.…”

BackgroundPseudophakic presbyopic correction is among the prevalent methods for regaining near vision capacity. The purpose of this study is to compare the impact of pseudophakic monovision correction and multifocal lens implantation on the performance in a series of activities of daily living (ADL) of presbyopic patients.MethodsAn ADL research framework (10 ADLs) was constructed and validated in a sample of patients divided into three validation groups according to their near visual acuity. Sixty-two participants that underwent mini-monovision (MoG) cataract extraction and 60 that underwent bilateral multifocal lenses implantation (MfG) populated study groups and addressed the ADLs. Binocular uncorrected distant (BdUVA) and near (BnUVA) visual acuity were associated with ADL scores and with subjective satisfaction using the VF-14 questionnaire.ResultsTest-retest reliability [all Intraclass Correlations Coefficients (ICC) >0.90] and construct validity (all p < 0.05) tests indicated sufficient psychometric performance of the ADL framework. Both study groups presented comparable mean ADL scores (p = 0.07) however, MoG patients had lower performance in demanding ADLs (p = 0.02). ADL scores demonstrated significant correlation with BnUVA (r2 = −0.67, p < 0.01) VF-14 scores (r2 = 0.53, p < 0.01).ConclusionsBoth methods provide sufficient near vision capacity for the majority of activities of daily living. However, only multifocal lens implantation can address demanding near vision tasks.Trial registrationClinicalTrials.gov Identifier: NCT02431156.

PresbyLASIK approach for the correction of presbyopia

Abstract: Additional trials and standards for reporting results for presbyopic approaches are necessary. Careful patient selection and counseling is imperative in all PresbyLASIK treatments.
