Elements Hybrid

Elements Hybrid is the result of over 5 years of intensive research & development by LCS laboratories, France. The innovative EyeBrid-inside technology underlying the hybrid lens enables the creation of a polymeric suture between the soft and RGP materials.

Elements Hybrid is a next-generation contact lens for daily wear. The lens consists of a central zone made of a high Dk RGP material and a soft Silicone Hydrogel peripheral skirt. 

Elements Hybrid offers an excellent and flexible fitting strategy with a broad range of radii and lens power for all patients.

Who is Elements Hybrid for?

  • Wearers of RGP lenses having problems relating to comfort, centration or stability
  • Keratoconus and other corneal irregularities, including highly complex irregular corneas
  • All astigmatisms that can potentially be fitted with RGPs
  • All high ametropias
  • Wearers of Piggyback lenses
  • Unilateral or occasional wear
Fitting Elements Hybrid is easy and effective when you follow these 3 simple steps: 

  1. Fit
  2. Evaluate
  3. Prescribe

1: Fit

Normal Corneas

Fitting Rule

  • BC = Kflat
  • Power = Spectacle refraction (vertex corrected)

 

Irregular Corneas

 

Fitting Rule

  • Fit the patient with an RGP from your standard RGP fitting set (TD < 9.5mm)
  • BC of RGP = BC of Elements Hybrid Lens
  • Power = P trial lens + over-refraction

2: Evaluate

  1. Assess visual acuity and over-refraction
  2. Perform a slit lamp examination and evaluate the lens as a soft lens
  3. Remove the lens after several hours of wear and check corneal integrity

 

The lens has to be well centred and should move as a soft lens

 

If no local staining is apparent the patient can continue to wear lenses

3: Prescribe 

Normal Corneas

 

Elements Hybrid with 10mm RGP zone

 

Example:

Keratometry: 7.45 @ 160/7.26 @ 070

Spectacle refraction: -8.25/-1.50 x 160

Prescribe: 

Elements Hybrid, 10mm RGP zone 7.45/14.90/-7.50

 

Irregular Corneas

 

Elements Hybrid with 8.5mm RGP zone

 

Example:

Keratometry: 6.80 @ 056/6.10 @ 146

RGP lens fitted: 6.60/8.80/-6.00

Over-refraction: -2.25 6/6

 

Prescribe :

Elements Hybrid, 8.5mm RGP zone 6.60/14.90/-8.25

 

Trouble Shooting

If centration and/or mobility are unsatisfactory, change the skirt:

– Skirt too steep?  Flatten by J +0.5

– Skirt too flat? Steepen by J -0.5

 

If staining, verify the fluorescein pattern at removal and change BC:

Staining in the centre? The lens is too flat.

Steepen BC by -0.10 and add -0.50D

Staining at junction area? The lens is too steep.

Flatten BC by +0.10 and add +0.50D

 

Too Flat

Optimal Fit

Staining

An Example

 

Keratometry: 7.45 @ 160/7.26 @ 070

Spectacle refraction: -8.25/-1.50 x 160

 

Lens Prescribed

Elements Hybrid with 10mm RGP: 7.45/-7.50/J 0

 

Observations

Decentred lens | No corneal staining

 

Changes

Skirt steepened by -0.5 | No change of BC

 

Prescribe

Elements Hybrid 10mm RGP: 7.45/-7.50/J -0.50

 

When to Opt for a Toric

 

Back Toric Lens

When? Only if the cornea is regular and if the corneal astigmatism is >4.0D (> 0.80mm).

Why? The objective of the back toric is to stabilise the lens.

 

Front Toric Lens

When? If the corneal shape doesn’t require a back-surface toric lens and if the astigmatism over-refraction is >0.75D.

Why? Front toric lenses compensate an over-refraction for wearers with astigmatism.

 

Bi-toric Lens

When? If the corneal shape requires a back-toric lens and if toric over-refraction is >0.75D

 

Lens Selection Algorithm 

  • Great comfort thanks to the Silicone Hydrogel soft skirt
  • The visual acuity of a rigid lens
  • Excellent centration and a simple fitting protocol even on difficult corneas
  • Spherical aberration control provided by a high definition aspheric design
  • A broad range of diameters, radius and lens power for all wearers
  • Total respect of ocular health:
  • A high level of oxygen permeability (Dk 100)

    A UV filter that filters 99% of UV-A and 97% of UV-B

    No micro-bubbles nor 3/9 o’clock staining

    No corneal erosion

    A  flexible wear schedule enabling both daily and occasional wear
