correction of presbyopia by monocular bi-aspheric ablation profile

Presbyopia is an age-related reduction in amplitude of accommodation leading to loss of near vision due to the loss of function of the lens and ciliary muscle1. The global population of presbyopes is projected to exceed 2 billion by 2030, with uncorrected and undercorrected presbyopia affecting socio-economic development2. Correction of presbyopia includes lens correction, surgical approaches, and medication. Corneal surgery is one of the main forms of corneal surgery to correct presbyopia because of its less invasive nature, fewer complications, and faster recovery3.
Ruiz introduced Presby laser-assisted in situ keratomileusis (LASIK) in 1996, which ablates the cornea into a multifocal pattern and increases the negative SA to achieve simultaneous near and distance vision4,5. Depending on the proximity area, Presby LASIK can be categorized into peripheral model6 (peripheral area for near vision and central area for distance vision) and central model7(peripheral area for distance vision and central area for near vision)8,9. The monocular bi-aspheric ablation profile is a hybrid Presby LASIK that combines the advantages of multiple programs, including micro-monocular vision, bi-aspheric, and multifocal. The dominant eye is completely corrected for distance vision, the central zone of the non-dominant eye retains approximately -0.89D of refraction for near vision, the peripheral cornea is ablated for distance vision, and the range of near addition (ADD) is between +1.25D to 2.50D, and aspheric cutting is used in both the central and peripheral zones10,11.
Compared with the previous monovision LASIK, the multifocal morphology of the non-dominant eye after the monocular bi-aspheric ablation profile reduces the anisometropia between the two eyes. The negative increase of SA introduces the depth of focus, which can better improve near vision and, at the same time, improve the intermediate vision, reduce the impact on stereopsis, and improve the patient&#39;s acceptance and satisfaction11,12,13. The monocular mode will lead to complete correction of the dominant eye, which can achieve the fastest postoperative clear full vision, reduce the risk of UDVA decline, and is more suitable for patients with presbyopia who have the same requirements for UDVA and UIVA, while other algorithms are multifocal in both eyes, which need more time for adaptation after surgery and have the risk of UDVA decline14,15,16. This article describes the detailed surgical steps of excimer laser multifocal double aspheric ablation mode as a surgical guide.

Correzione della presbiopia mediante profilo di ablazione biasferica monoculare

We are committed to a refractive surgical correction of presbyopia and exploring its postoperative visual acuity effect and coronal morphology in order to provide a reliable reference value for the clinical application of this technology. The correction technique applied in this paper has improved the phenomenon of insufficient distance vision and difficulty in adaptation after multifocal correction in the past, and is more suitable for patients with high requirements for distance vision. In the future, we will pay more attention to the comparative research of several different correction method and try to provide the best treatment plan for patients with presbyopia in different conditions.

The study aims to evaluate visual acuity and objective visual quality before and after the monocular bi-aspheric ablation profile for correction of ...

Siamo impegnati in una correzione chirurgica refrattiva della presbiopia e nell'esplorazione del suo effetto di acuità visiva postoperatoria e della morfologia coronale al fine di fornire un valore di riferimento affidabile per l'applicazione clinica di questa tecnologia. La tecnica di correzione applicata in questo articolo ha migliorato il fenomeno della visione da lontano insufficiente e della difficoltà di adattamento dopo la correzione multifocale in p...
