Intraocular lens power calculation after macular hole surgery.
A patient had cataract surgery in both eyes after bilateral macular hole repair. In the left eye, the intraocular lens power was calculated using the axial length obtained by biometry. In the right eye, 0.5 mm, the estimated depth of the foveolar crater after stage 3 macular hole repair, was subtracted from the A-scan measurement to obtain the functional axial length. Postoperatively, refraction was +0.25 diopter (D) in the right eye and +1.63 D in the left eye. Biometry after macular hole surgery should be corrected by subtracting the depth of the foveolar crater from the measured axial length.
