Menicon Contact Lens Products

Parameter reference for Menicon contact lens lines available in Singapore, covering disposable soft lenses (Miru 1day, Miru 1month, Menicon PremiO) and specialty RGP lenses (Menicon Z, ROSE K, Menifocal Z, orthokeratology). Use the filter buttons to narrow by lens category or modality. Specialty and RGP parameters are custom-fitted — all specifications require confirmation with your Menicon Singapore representative.

RGP

Menicon Specialty & RGP Portfolio — Clinical Context

Menicon's specialty portfolio is built around the Menicon Z fluorosilicone acrylate material (Dk = 163 ISO Fatt), one of the highest-Dk conventional GP materials available and the foundation for multiple lens designs. The Menicon Z and Menicon Z-α are standard GP lenses for regular and astigmatic corneas; Menicon Tinu offers an ultra-thin profile with UV protection. Menifocal Z is a concentric bifocal RGP for presbyopia. ROSE K covers the full spectrum of irregular cornea fitting — from early keratoconus to post-graft and pellucid marginal degeneration — with dedicated designs (K2, NC, PG, IC, XL). For myopia control and orthokeratology, Menicon Z Night uses Menicon Z material (Dk 163) with overnight reverse-geometry reshaping (up to 30 nights continuous wear), while Menicon α ORTHO-K employs a four-zone, five-curve geometry for treatment up to −6.00 D. All specialty lens fittings require corneal topography and structured aftercare — confirm all parameters with your Menicon Singapore representative.

^†For RGP and ortho-K lenses, material Dk (ISO 18369-4 Fatt method, ×10⁻¹¹ units) is quoted rather than Dk/t. Effective Dk/t depends on centre thickness, which varies with back vertex power and lens design. Menicon Z material Dk = 163; Menicon α ORTHO-K material Dk = 104. ROSE K material Dk is not specified — confirm with Menicon Singapore.

Orthokeratology lenses are reverse-geometry rigid lenses designed to reshape the anterior corneal surface during overnight wear. All parameters are custom — BC, return zone, alignment curve, and diameter are determined by corneal topography and refraction. Corneal topography, fluorescein pattern assessment, and regular aftercare are essential. Menicon Z Night supports up to 30 nights continuous wear; Menicon α ORTHO-K has a treatment range up to −6.00 D.

Verification required

Disposable lens parameters are sourced from Menicon Singapore product pages and should be verified against current product inserts before clinical use. Specialty and RGP lens parameters are custom-fitted — no stock parameters apply; all specifications are determined at the time of fitting. Product availability, fitting guides, trial lens protocols, and software (Easyfit) should be confirmed with your Menicon Singapore representative or authorised distributor. This page does not constitute clinical advice.
