Regular astigmatism reaching 3.00 D or more falls within the high refractive error range. At this level of astigmatic error, the selection of the appropriate correction strategy becomes particularly important.
This protocol is specific to patients with regular astigmatism of 3.00 D or more — the established threshold that qualifies as a high refractive error. Precise measurement of the astigmatic magnitude is central to determining the applicable management pathway.
Several correction modalities are addressed for astigmatism at this magnitude. The regimen for this scenario includes consideration of corneal surgical approaches as part of the management options.
High refractive errors are defined as 6.00 D or more of myopia, 3.00 D or more of hyperopia, and 3.00 D or more of regular astigmatism.
Correction options include eyeglasses, contact lenses, and surgery. These include refractive surgery to the cornea, such as LASIK and photorefractive keratectomy, and lens surgery, such as clear lens extraction, phakic intraocular lenses, and cataract surgery.
