Mark'ennovy shares how its Gentle multifocal and multifocal toric contact lenses with Smart MF Tech technology offer new opportunities for practitioners and presbyopic patients alike
The National Institute of Statistics has recognised that in the coming decades the largest segment of the population will be aged between 45 and 60 years old. Progressive ageing, combined with a growing culture of health consciousness and daily dependence on digital devices, has increased the demand for comfortable vision at all distances for presbyopes.
Significant progress has been made in product development for presbyopia correction. This includes novel multifocal contact lens designs, driven by a better understanding of the factors affecting the lens performance – beginning from the contact lens design phase to the clinical behaviour of the contact lens on the eye.
Optimised for the patient
A patient’s individual eye characteristics, such as pupil diameter, as well as ocular aberrations and residual accommodation, play an important role of the performance of multifocal lenses. These factors are an integral part of the lens performance and will vary depending on the patient’s age.
"mark'ennovy is committed to continuous innovation through design advanced premium hydrophilic contact lenses with an unmatched level of customisation"
The incorporation of these variables in the design of contact lenses for presbyopia would allow optimising the power distribution over the optical zone of the lens to maximise the quality of vision. Advances in the reproducibility of the lens and predictability of visual outcome would improve the contact lens fitting process for the eye care professional.
