Low-cost method for manufacturing self-adherent PDMS lenses for presbyopia

We present an easy method for manufacturing elastomeric self-adherent lenses with optical quality. The lenses were manufactured in polydimethylsiloxane using ophthalmic and trial lenses of different base curve as master molds to generate different refractive powers. The diameter of the manufactured lenses ranged between 30 mm and 60 mm. We characterized the lenses alone and after being self-adhered to different spherocylindrical ophthalmic lenses, by measuring the refractive power and the Zernike aberrations. Besides, an artificial myopic eye was used to quantify the image quality provided by the lenses self-adhered to several ophthalmic lens. The manufactured lenses showed good optical quality with no aberrations. Low order refractive errors were found in one case after self-adhesion. The results confirm the suitability and simplicity of the proposed method to manufacture high quality elastomeric lenses that can be self-adhered to ophthalmic lenses to add power and help with presbyopia.

Automated summary

We propose a simple method for manufacturing high-quality elastomeric self-adherent lenses. Polydimethylsiloxane was used to create lenses, with ophthalmic and trial lenses of different base curves as master molds to achieve varying refractive powers. The manufactured lenses showed good optical quality with no aberrations. The results confirm the suitability and simplicity of this method for creating high-quality elastomeric lenses that can be self-adhered to ophthalmic lenses to add power and assist with presbyopia.
