How do myopic presbyopes adapt to progressive lenses?
In this article:
This study examined the quality of life of myopic presbyopic patients based on their level of myopia and type of visual correction. It found that highly myopic subjects had lower quality of life scores than low myopes. Both high and low myopes had better QOL scores when wearing PALs as opposed to SVD glasses, with reports of patients being less “frustrated with their glasses”.

Summary
This study utilised a questionnaire to evaluate the impact of level of myopia and type of visual correction on vision related quality of life (QOL) in a group of 149 presbyopes aged 41-75 years. Highly myopic subjects (SER-5.00D) had significantly lower mean QOL scores (51.65) compared to low myopes (SER -5.00D) (65.24). Similarly, functionality scores were lower in the highly myopic group than the low myopic group, both with (49.38 vs 57.00) and without (29.12 vs 36.24) glasses.
Highly myopic presbyopes wearing PALs had significantly better perception of their visual function (61.2) than those who wore SVD lenses (46.9), who were half as likely to be “afraid to do things because of their vision” and “frustrated with their glasses” in single vision compared to if they were wearing PALs. Similarly, low myopes wearing PALs had better QOL than SVD users. Clinically, this advocates for the recommendation of PALs as opposed to SVD lenses for myopic presbyopic patients. Additionally, the assumption that myopes prefer reading without their glasses was challenged, with 42% of low myopes and 88% of high myopes reported difficulty reading without glasses. Clinically, this means eye care practitioners should consider PALs as possibly being a superior option to improve QOL of our myopic presbyopic patients of various levels of myopia.
What does this mean for my practice?
When recommending visual correction for your myopic presbyopic patients, discuss the option of PALs to increase vision related quality of life!
What do we still need to learn?
This was a self-reported survey measuring vision related quality of life scores, and further research is required to investigate the clinical impact of this findings.
Abstract
Title: Quality of Life in Presbyopes with Low and High Myopia Using Single-Vision and Progressive-Lens Correction
Authors: Adeline Yang, Si Ying Lim, Yee Ling Wong, Anna Yeo, Narayanan Rajeev, Björn Drobe
Purpose: This study evaluates the impact of the severity of myopia and the type of visual correction in presbyopia on vision-related quality of life (QOL), using the refractive status and vision profile (RSVP) questionnaire.
Methods: A total of 149 subjects aged 41-75 years with myopic presbyopia were recruited: 108 had low myopia and 41 had high myopia. The RSVP questionnaire was administered. Rasch analysis was performed on five subscales: perception, expectation, functionality, symptoms, and problems with glasses.
Results: Highly myopic subjects had a significantly lower mean QOL score (51.65), compared to low myopes (65.24) (p < 0.001). They also had a significantly lower functionality score with glasses (49.38), compared to low myopes (57.00) (p = 0.018), and they had a worse functionality score without glasses (29.12), compared to low myopes (36.24) (p = 0.045). Those who wore progressive addition lenses (PAL) in the high-myope group (n = 25) scored significantly better, compared to those who wore single-vision distance (SVD) lenses (n = 14), with perception scores of 61.19 and 46.94, respectively (p = 0.029).
Conclusions: Highly myopic presbyopes had worse overall QOL and functionality, both with and without glasses, compared to presbyopes with low myopia. High-myopic PAL users had a better perception outcome than SVD lens wearers. Low-myopic PAL wearers had a better QOL than SVD wearers.
