Practitioners should be aware of the potential for vertical prismatic effect when selecting which toric designs to prescribe, particularly for monocular astigmats with preexisting binocular vision anomalies, and when managing complaints of asthenopia in monocular astigmats.
Clinical studies with the latest designs have dispelled some of the misconceptions about the ease and speed of fitting of toric soft lenses and shown that most astigmats who are not currently using soft torics can be successfully fitted.
A UK study, (11) recruited 200 astigmats who had never worn toric lenses, with distance corrections of +4.
A surprising revelation was the serendipitous research finding that many prism-ballasted toric lenses can have up to one dioptre of vertical prism within the optic zone, indicating that practitioners should consider the use of symmetrical stabilisation designs when correcting monocular astigmats
2) Despite the advances made, many astigmats
still do not utilise this type of lens.
According to the company, until now no other SiHi monthly replacement lens has allowed practitioners to fit all astigmats
Astigmats are in the dark Practitioners have the opportunity to improve awareness of toric lenses primarily through how they explain astigmatism to patients; according to research findings, consumers are only provided with very basic information about astigmatism, with only about 40% of patients reporting that the impact on their vision was explained.
But practitioners do need to consider why, when compared to spherical contact lens wearers, astigmats are less satisfied with their lenses.
The Saturn II, when correctly fitted, had the advantages of providing excellent centration and provided clear, stable vision to high astigmats and irregular corneas.
Potential patients for SynergEyes might be astigmats who have never achieved adequate visual acuity (VA) with soft torics, cannot tolerate RGP's, RGP wearers who want improved comfort but won't compromise on VA, or dissatisfied soft lens wearers.
