Higher-order aberration correction in abnormal eyes can result in significant vision improvement, especially in eyes with abnormal corneas. Customized optics such as phase plates and customized contact lenses are one of the most practical, nonsurgical ways to correct these ocular higher-order aberrations. We demonstrate the feasibility of correcting higher-order aberrations and improving visual...

PURPOSE To evaluate preliminarily the safety and efficacy of customized photorefractive keratectomy (PRK) to correct ametropia and irregular astigmatism after penetrating keratoplasty (PK). METHODS This pilot study included five eyes of five patients with a mean spherical equivalent of -5.1±1.46D (range from -2.75 to -6.50D). In all cases, ametropia and irregular astigmatism was corrected wit...

BACKGROUND Prostheses are used to varying degrees; however, little is known about how environmental aspects influence this use. OBJECTIVES To describe users' experiences of how environmental factors influence their use of a myoelectric arm prosthesis. STUDY DESIGN Qualitative and descriptive. METHODS A total of 13 patients previously provided with a myoelectric prosthetic hand participate...

Despite introduction of oral phosphodiesterase type 5 inhibitors and intracavernosal vasoactive agents, penile prosthesis implant remains a relevant and desired option with sales of penile prostheses continue to stay high, as many men became refractory to medical therapy and/or seeking a more effective and permanent therapy. There are two types of penile prosthesis implants: inflatable and non-...

We describe a new surgical technique for treating traumatic aniridia with aphakia and its results in a small consecutive case series. We attached a 3-piece acrylic intraocular lens through the haptics to a customized silicone iris prosthesis. The combined implant was inserted through a 5-mm incision and fixated with a transscleral suture in the ciliary sulcus using a knotless technique (Z sutur...

The restoration and recovery of a defective skull can be performed through operative techniques to implant a customized prosthesis. Recently, image processing, surface reconstruction and geometric methods have been used for digital prosthesis design. In this chapter we review state-of-the-art approaches in this field and discuss related issues. The field of prosthesis modeling may include metho...

Restoring a large edentulous space in the anterior maxilla presents many challenges, including how to utilize and manage a deep anterior soft tissue undercut. In the case reported here, a partial denture was constructed that incorporated a semi-rigid exterior flange and a soft liner to help the denture to engage the depth of the undercut. The denture was placed after extraction of the anterior ...

Usually visualization is applied to gain insight into data. Yet consuming the data in form of visual representation is not always enough. Instead, users need to edit the data, preferably through the same means used to visualize them. In this work, we present a semi-automatic approach to visual editing of graphs. The key idea is to use an interactive EditLens that defines where an edit operation...

 AIM: To increase effectiveness cosmetic at formation a primary and/or delayed supporting stump simultaneous reconstructive procedures on orbital bone structures.
 MATERIALS AND METHODS: A retrospective analysis subatrophy deformities walls was carri...
