Without enough oxygen, you might feel symptoms such as end-of day discomfort, irritation, dryness, and redness. Also known as Corneal Oxygen Deficiency. In the long run, lack of oxygen may even cause complications. People who wear their contacts longer than the recommended wearing time are most at risk. AIR OPTIX is made with a revolutionary silicone hydrogel technology allowing 5 times more oxygen to reach the eye than the leading 2-week lens to help protect you from the signs and symptoms of Corneal Oxygen Deficiency.

Silicone hydrogel lenses are now accepted as the gold standard lenses of choice to reduce or prevent contact lens-related problems such as hypoxic signs.1-4 The use of these lenses in everyday practice brings the benefits to patients of longer wearing times, relief of dryness symptoms, more stable vision, whiter eyes and better lens comfort.

For astigmatic patients requiring a toric soft lens, the benefits of SiHy materials are even more pronounced. Toric lenses are thicker than their spherical equivalent due to designs intended to make the lenses rotationally more stable. This increase in thickness reduces the oxygen transability of the lens and increases the possibility of corneal oxygen deficiency. Other Silicone hydrogel lenses:

AIR OPTIX for ASTIGMATISM lenses are made of lotrafilcon B, and have a Dk/t of 108 @ -3.00D. Launch parameters are from plano to -6.00D in 0.25D steps, with cylinder powers of -0.75 and -1.25 and axes around-the-clock in 10° steps. These parameters will be expanded in the near future to include plus powers, high-minus powers and additional cylinder powers. The lenses have a diameter of 14.5 mm and a base curve of 8.7 mm, and feature a blue handling tint. AIR OPTIX for ASTIGMATISM lenses are approved for daily wear and up to 6 nights of extended wear, and are recommended for monthly replacement.

Prior to the launch of the new lens, evaluation trials were conducted in the Nordic region and the UK.

Methods

This was an open-label, bilateral, single group, multi-centre trial conducted in Denmark, Finland, Norway and Sweden, from December 2005 to June 2006. The test lenses, Air Optix for Astigmatism, were CE marked and used within their indication. The lens parameters that were evaluated are shown in Table 1.

Thirty-nine investigators enrolled a total of 328 subjects to wear the lens, with visits at dispensing and after 2-4 weeks of wear. Subjects were either habitual contact lens wearers (88 per cent) or spectacle wearers with astigmatism.

Subjective and objective performance was documented both at dispensing and when subjects returned for a final visit after approximately four weeks of wear. Subjective results were measured using questionnaires, and objective measures, such as lens fit and on-eye orientation, were recorded by investigators.

Results

All 328 subjects who were enrolled in the trial returned for a follow-up visit and completed the trial period. Of these, 227 (69 percent) subjects were female and 97 (30 percent) were male (1 percent were not reported).

Subjects reported wearing the test lenses, on average, 6.23 days per week (range one to seven days). The wearing time per day was reported to be, on average, 12.79 hours (range 2 to 24 hours). Comfortable wearing time was on average 11.37 hours (range zero to 24 hours).

Of those who expressed a preference, a majority of previous contact lens wearers preferred the test lens to their habitual lenses for vision (3.6:1), comfort (4.3:1) and overall (3.2:1). These percentages were significantly different from 50 per cent, with p<0.001 (exact binominal test).

There was also a high degree of satisfaction with the test lens. A majority of subjects (73 per cent) were either 'fully' or 'mostly' satisfied with the lens at the final visit. Nearly twice as many subjects were fully satisfied with the test lens as they were with their habitual lenses (Figure 5).

Subjects were also asked to express their agreement with the following statements regarding the performance of the test lenses:

* Are comfortable when first put in
* Are still comfortable at the end of the day
* Are comfortable all day long
* Provide crisp, clear vision
* Provide stable vision
* Are easy to insert
* Are easy to remove from the eye.

For all statements, a majority of subjects were in agreement. Agreement varied between 94 per cent for 'easy to insert' and 72 per cent for 'still comfortable at the end of the day'. At both dispensing and final visit, more than 98 per cent of fits were acceptable and more than 72 per cent were optimal. More than 82 per cent of lenses oriented within 5° of horizontal almost 45 per cent were exactly horizontal and a further 37 per cent were within 5°. Where there was a deviation from horizontal, the average orientation was 5° ±3.4° to 4.6° nasal up. At both the dispensing and final visits, more than 93 per cent of lenses rotated less than 3° with the blink.

At the end of the trial 78 per cent of the subjects went on to purchase Air Optix for Astigmatism.

Conclusions

Air Optix for Astigmatism was well received by subjects. A large majority were satisfied with the comfort, vision and handling provided by the lens. This satisfaction resulted in a clear preference over their habitual lenses. The lens also demonstrated a fast and effective fitting procedure. Most subjects went on to purchase lenses after the trial was completed.
