latent hyperopia lasik：Considerations in Hyperopic Treatments

The goal of refractive surgery in eyes that have not undergone previous ocular surgery is to achieve postoperative distance UCVA equal to the patient’s preoperative distance BCVA. Hyperopic excimer laser ablations use a ring profile in the paracentral-to-peripheral cornea. The hyperopic ablation algorithm steepens the central corneal profile to achieve the desired correction. This is in contrast to myopic corrections, which flatten the central cornea.

Historically, hyperopic corrections have been more of a challenge for refractive surgeons than myopic corrections. This article reviews some of the reasons for that difference and offers some guidelines for achieving accurate refractive surgical corrections in hyperopic patients.

Refractions in hyperopia are typically underestimated

Clinical subjective refractions in hyperopia are typically underestimated due to the accommodative response of hyperopic patients, who are used to accommodating for fa...
