a larger optic and longer overall length, it offers several
additional benefits:

HYDROPHILIC ACRYLIC INJECTABLE IOLS WITH
AMON-APPLE ENHANCED SQUARE EDGE AND
ABERRATION-NEUTRAL OPTIC TECHNOLOGY

Recent advances in IOL design have involved the application of wavefront technology to help improve optical efficiency and visual function. The ability to measure Higher Order Aberrations has led to a much greater understanding of the eye as an optical system, resulting in a new category of IOLs – aspherics – which are capable of providing an excellent quality of vision and improved contrast sensitivity particularly in mesopic illumination.

In the younger eye, the naturally-occurring positive spherical aberration of the cornea is largely balanced by the negative spherical aberration of the crystalline lens, resulting in optimal vision. However, with age, that negative spherical aberration becomes more positive, creating an imbalance which can reduce contrast sensitivity and thus, visual function. This compounds the reduced contrast sensitivity of the ageing macula.

Aspheric IOLs, unlike conventional IOLs (which have positive spherical aberration), induce significantly less spherical aberration by effectively avoiding adding to the positive spherical aberration of the cornea. As such, they are associated with an increased contrast sensitivity and functional visual acuity, particularly under mesopic and scotopic conditions. This can lead to an improved night vision and decreased glare. As contrast sensitivity tends to decline with age, aspheric IOLs can minimise loss of contrast sensitivity to optimal levels.

However, aspheric IOLs can either be based on negative spherical aberration designs (to try to correct existing corneal asphericity), or they can be truly aspheric, or aberration-neutral, to reduce the occurrence of additional and unwanted optical aberrations. There are concerns that IOLs with negative spherical aberrations may, by producing a very flat wave-front, have an undesirable effect on the depth of field. The Rayner C-flex™ Aspheric and Superflex™ Aspheric IOLs are spherically aberration-neutral with the aspheric modification being applied to the anterior surface of the IOL, providing uniform refractive power from the centre of the optic to its edge, for optimal visual outcomes. The depth of field of this lens is very similar to standard IOLs whilst having the advantages discussed above.

Additionally, unlike negative spherical aberration designs, aberration-neutral IOLs do not contribute to any pre-existing higher order aberrations in the visual axis, thereby optimising image quality, regardless of the patient´s idiosyncratic spherical aberration, or indeed, by any limitations imposed by previous surgery. Similarly, unlike negative spherical aberration designs, with aberration-neutral IOLs, the image quality is much less likely to be affected by decentration or tilt.

In addition to all these advantages, the Rayner C-flex™ Aspheric and Superflex™ Aspheric IOLs offer the technology of the existing IOL platform. These include the Amon-Apple Enhanced Square Edge for exemplary low posterior capsular opacification rates, AVH (anti-vaulting haptic) Technology for optimal centration, and a single use Soft-tipped injector capable of IOL insertion through a sub 3mm incision.

Hydrophilic Acrylic Injectable Multifocal
IOL with Amon-Apple Enhanced Square Edge

The Rayner M-flex™ Multifocal IOL (630F) provides a degree
of pseudoaccommodation, lessening the need for additional
correction by spectacles or contact lenses.

The Rayner M-flex™ Multifocal IOL is based on a multi-zoned aspheric optic technology with either 4 or 5 annular zones (depending on IOL base power) providing 3.0 diopters of additional refractive power (equivalent to 2.25 diopters at the spectacle plane).

The additional power of 3.0 diopters at the IOL plane is selected for optimum performance with reduced incidence of halo or glare.

In addition to multifocality, The Rayner M-flex™ Multifocal IOL offers all the additional advantages of C-flex™ and Superflex™

Hydrophilic Acrylic Injectable Toric IOLs
with Amon-Apple Enhanced Square Edge

Rayner T-flex™ Toric IOLs (573T and 623T) are a superior
alternative to toric IOLs with a restricted range of torus
and a precise alternative to incisional correction of
corneal astigmatism.

By incorporating a torus (cylindrical correction) on the anterior optical surface, T-flex™ Toric IOLs provide a superior, reliable alternative to incisional keratotomy and Limbal Relaxing Incisions (LRIs) for the treatment of pre-existing corneal astigmatism.
T-flex™ Toric IOLs are particularly useful for those cataract patients where incisional methods would provide inadequate astigmatic correction. The choice of a T-flex™ Toric IOL leads
to more precise surgical results, especially for cases of severe astigmatism: patients with a history of corneal pathology, keratoconus with penetrating keratoplasty (corneal grafts) and patients with burns and corneal scarring.

Unlike plate-haptic and multipiece toric IOLs, T-flex™ Toric IOLs have inherent rotational stability. Superb visual outcomes are achieved because of the dependable absence of rotation in lenses designed with Rayner’s patented AVH Technology™.
T-flex™ IOLs are also available in a far greater range of cylinder and sphere combinations than some other toric IOLs, which are made with only a limited range of cylindrical additions; such lenses with a 2.0D or 3.5D torus are designed solely for those cataract patients with small, regular, pre-existing astigmatism.
T-flex™ Toric IOLs correct much higher astigmatism.

Rayner T-flex™ IOLs are currently manufactured as either
model 573T or model 623T (having a 5.75mm optic or a
6.25mm optic respectively).

The model selection is made automatically by Rayner so
that the largest possible diameter optic is supplied for any particular sphere / cylinder / lens injector nozzle combination.

Model 623T is designed for low and medium power lenses
and model 573T is designed for higher power lenses.

In addition to an excellent toric correction, T-flex™ Toric IOLs offer all the additional advantages of C-flex™ and Superflex™.

Injectable Capsular Support System

Rayner´s Centerring™ system is designed for complicated cataract surgery involving anterior capsular tears and zonular dehiscence.

The Centerring™ inserter is made from the highest quality
non-corrosive and non-magnetic titanium to be strong and durable. Anodised in dark blue, the inserter does not glare
under the operating room microscope lighting.

All rings are made of PMMA and have two positioning holes
for ease of use.

Three sizes of rings provide excellent capsular support:

With advanced IOL design and modern surgical technique,
an exact refractive result following cataract surgery with implantation of an IOL is a reasonable expectation. Rayner Sulcoflex® Pseudophakic Supplementary IOLs are designed to correct any post-surgical or residual ametropia, without the trauma, or increased surgical risk, of an IOL exchange.

Moreover, unlike with conventional "piggy-back" IOL implantations, the unique design of Rayner Sulcoflex® Pseudophakic Supplementary IOLs ensures that the potential for contact between the two implants is minimised. This reduces the likelihood of induced refractive error and optical aberrations due to optic surface distortion at the area of contact between the IOLs.

Rayner Sulcoflex® Pseudophakic Supplementary IOLs are manufactured from Rayner’s proprietary hydrophilic acrylic co-polymer, Rayacryl®, which is noted for its exceptional uveal biocompatibility – a factor so important in those IOLs specifically intended for ciliary sulcus fixation. Rayacryl® is also noted for its superb optical clarity, with no vacuoles or glistenings. These factors, coupled with a remarkably low silicone oil adherence and excellent handling characteristics, means that Rayacryl® represents the ideal in IOL biomaterials.

The large optic diameter of Rayner Sulcoflex® Pseudophakic Supplementary IOLs ensures quality of vision with reduced risk of optic-iris capture and the round optic edge contributes to low rates of dysphotopsia.

The large diameter “undulating” haptics ensures IOL centration and rotational stability and the haptic angulation ensures uveal clearance, thereby avoiding pigment dispersion, and further reducing the risk of optic-iris capture.

The soft, round-edged haptic design ensures minimum tissue contact reaction.
