C7 ECO also eliminates the risks of C7 and T1 pedicle subtraction osteotomies (C/T PSOs), in which a posteriorly based wedge excision may lead to stretching injuries of the lower cervical roots and/or failure to achieve the exact angle of excision required for an optimal correction. A modification of cervicothoracic extension osteoclasis (C/T EO), C7 ECO replaces osteoclasis of the anterior column with a crosswise cut of the C7 vertebral body to eliminate the risks of unintended dislocation of the cervical spine. There is a significant improvement in visual acuity with results satisfying the patient's high expectations.Įxtension crosswise osteotomy at C7 (C7 ECO) was developed for the correction of forward gaze in patients with chin-on-chest deformity due to ankylosing spondylitis. Well tolerated by the patient, the implant played a key role in effectively overcoming the irregular corneal astigmatism. Optimal correction of the distance vision and near vision was achieved, and the results were monitored within six months after surgery.ĬONCLUSION: The pinhole implant was securely positioned in the capsular bag. No complications related to the position of the implant were observed in the postoperative period. The cataract removal was performed by standard phacoemulsification followed by implantation of a pinhole implant in the capsular bag.
RESULTS: All necessary measurements were performed using an iTrace aberrometer and IOL Master 700. METHODS: A report of a rare case, the first implantation of XtraFocus implant in Bulgaria for the correction of keratoconus combined with cataract. PURPOSE: To present a case report of a patient who underwent cataract surgery, with implantation of an intraocular implant called pinhole and correction of an irregular corneal astigmatism as a result of keratoconus. The latter becomes of major interest when patients with keratoconus present with a cataract which contributes to a further visual decline. Patients typically experience variable reductions in visual acuity, image distortion, and increased sensitivity to glare and light. The hallmark of keratoconus is central or paracentral stromal thinning, accompanied by apical protrusion and irregular astigmatism. The technique of occipitofrontal switch for correction of anterior plagiocephaly is an elegant procedure with good functional and aesthetic outcome. One year follow-up of the patient showed optimal correction of the defect in the forehead region, symmetrical shape of the frontal and occipital region and symmetrical brows. There were minimal blood loss and postoperative morbidity. Measurements were accurately drawn and the procedure was practised virtually before performing the occipitofrontal switch on the patient.

3D image of her skull was reconstructed using Geomagic Freeform software (3D Systems, Rock Hill, SC). This is the first such case reported from India and first report where virtual mock surgery has been utilized for precision and improving outcome in this elegant procedure.Ī 5-year-old girl presented with left anterior plagiocephaly. Occipitofrontal switching is a novel technique which utilizes a part of the contralateral occipital bone to reconstruct the frontal area. Cranial vault remodeling, however, is associated with several complications. Various surgical procedures have been described for the correction of this deformity. Unilateral coronal synostosis causing anterior plagiocephaly can result in restricted brain development and severe facial deformities.
