Design innovations that provide maximum comfort and optimum lens performance

The perfect balance between innovation and insight

Research shows that the shape of the limbus and the sclera is typically linear and not curved.1 Furthermore, in  98.5% of cases, the scleral surface is toric and not spherical.3 This was the basis for the design of Menicon Time XL. The goal of the bitangential design was to realise an optimal distribution of pressure of the lens on the conjunctiva. This results in higher tolerance, which allows for longer daily use.2,3.4

Menicon Time XL has a bitangential landing zone for a simple fit and good stability. The lens fit can be assessed in as little as 30 mins of wearing time.

 

Product features

TimeXL_lens-design

Unique design

3 zones: Central optical zone,  Mid-peripheral limbal zone and Scleral landing zone.

TimeXL_periphery

Bitangential periphery

The first scleral lens with a bitangential periphery for a soft landing on the sclera. The lens was designed using the latest research on the shape of the eye.

TimeXL_Menicon-Z

Menicon Z material

Hyper-oxygen material ensures ample oxygen flow to the eye, while advanced surface treatment enhances wettability for superior comfort.

TimeXL_conditions

Accommodates a wide variety of ocular conditions

Menicon Time XL is available in single vision and multifocal designs to help address various corneal irregularities, refractive errors and ocular surface diseases. 

Fitting philosophy

Menicon Time XL can be fitted utilising two approaches: Diagnostic set and Easyfit software.

The diagnostic set consists of 16 trial lenses with different heights and tangent angles. All lenses have a diameter of 16.0 mm*, a base curve of 8.4 mm, plano power, and a toric periphery. The toricity is expressed in tangent angles with a difference of 6° between the flat and steep meridian for all diagnostic lenses.

Alternatively, you can use Easyfit software to determine the first trial lens. The programme uses the corneal topography measurements, HVID and refraction to recommend the initial trial lens to start with.

*Diagnostic set of 17mm diameter is also available on request.
