IOA Technique MARKING THE AXIS OF ASTIGMATISM FOR THE IMPLANT OF A TORIC INTRAOCULAR LENS
ثبت نشده
چکیده
Until recently, the pursuit of emmetropia in patients with astigmatism (around 30% of the population) was infeasible since the only intraocular lenses available on the market were designed to correct myopia or hyperopia. However, with the new toric lens designs now available, a patient’s cataract, myopia, hyperopia and astigmatism can all be corrected by means of a simple, safe operation followed by a rapid recovery. Today’s main challenge is making sure that the astigmatism-correcting intraocular lens (IOL) is precisely aligned on the patient’s axis of corneal astigmatism. The slightest variation will mean that the patient will develop a postoperative astigmatism on a different axis to that of the preoperative astigmatism.

متن کاملSurgical management of astigmatism with toric intraocular lenses.
Correction of corneal astigmatism is a key element of cataract surgery, since post-surgical residual astigmatism can compromise the patient's uncorrected visual acuity. Toric intraocular lenses (IOLs) compensate for corneal astigmatism at the time of surgery, correcting ocular astigmatism. They are a predictable treatment. However, accurate measurement of corneal astigmatism is mandatory for ch...

AIM The aim of this research was to evaluate vector analysis after implantation of toric intraocular lenses (IOLs) without deviation from the intended axis. METHODS The study included 18 eyes of 16 patients who underwent cataract surgery with the insertion of a toric implant (AcrySof IQ Toric). The postoperative IOL meridian placement completely corresponded to that planned. Using vector anal...
