Comparison of a new implantable collamer lens formula to standards formulas using spectral domain optical coherence tomography.

Purpose: To use spectral-domain optical coherence tomography (SD-OCT) data to develop a new implantable collamer lens (ICL) sizing formula and compare vault outcomes with the Online Calculation and Ordering System™ (OCOS) and the NK2 formula.

Methods: Consecutive eyes (n = 237) were evaluated that had undergone ICL/toric ICL implantation. Actual ICL vaults were measured, and a what-if analysis was performed to predict vault values with the NK2 formula using SD-OCT data.

Surgical and prosthetic dental rehabilitation through a complete digital workflow - A case report.

Several aspects of digital dentistry have recently been improved, including new materials, navigated implant placement, digital impression in combination with virtual articulation, and the computer-aided processes of designing and manufacturing of prosthetic restorations. In this case report, the prosthodontic treatment of a patient through a complete digital workflow is presented. A 39-year-old male patient presented for restoration of missing teeth in the posterior maxilla and mandible.

Clinical outcomes of lithium disilicate single crowns and partial fixed dental prostheses: a systematic review.

Statement Of Problem: Lithium disilicate is a relatively new and popular restorative material for esthetic and functional rehabilitations, but the evidence for clinical outcomes is not clear.

Purpose: The purpose of this systematic review was to analyze the short-term (1- to 5-year) and medium-term (5- to 10-year) survival rates of lithium disilicate single crowns and partial fixed dental prostheses.

Material And Methods: An electronic search for articles in the English-language literature published between January 1998 and June 2013 was performed with the PubMed search engine.

Small optical zones with aspheric profiles in laser refractive surgery for myopia: a surgical outcome and patient satisfaction study.

Purpose: To assess the outcomes of small optical zone (OZ) ablations used in conjunction with large transition zones (TZ) and a highly aspheric treatment profile.

Methods: Interventional case series of 39 consecutive patients with myopia or myopic astigmatism. Patient data included pre and postoperative refraction and visual acuities, laser treatment settings and pre and postoperative corneal topography as well as questionnaire responses about the use of glasses and the quality of vision postoperatively.

A contralateral, randomized comparison of optimized prolate ablation and conventional LASIK for myopia with the NIDEK excimer laser platform.

Purpose: To compare the refractive, visual acuity, topographic, and spherical aberration outcomes of LASIK using the Quest excimer laser platform with the optimized prolate ablation (OPA) profile (NIDEK Co Ltd) in one eye and conventional ablation profile in the fellow eye of the same patient.

Methods: Thirty-seven myopic patients underwent LASIK bilaterally, with one eye randomized to receive OPA ablation (-3.88±1.
