Biomedical technology problem solving event that challenges students to develop innovative technological solutions to improve vision and eye health. Students work in teams and are provided with resources and expert advice to design, prototype, and test their solutions. A panel of judges evaluates their work, and the winning team is awarded a prize and paid internship to further develop their idea.

1. Design of Novel Draping system : Postoperative endophthalmitis can severely damage ocular tissues. The most common infecting agents are Staphylococcus aureus, from the bacterial flora of the eyelid, and Propionibacterium acnes, present on the meibomian and sebaceous glands. It has been reported that endophthalmitis occurs when these agents gain entry into the eye through a contaminated surgical field. Therefore, pre- and intraoperative infection control is crucial to prevent endophthalmitis. Preoperative prophylaxis to minimize contamination of the surgical field includes topical antibiotics, thorough disinfection, and appropriate draping. Among these measures, appropriate draping prevents exposure of the eyelashes and eyelids to the surgical field and thus reduces bacterial contamination. Conventional draping includes using an adhesive drape to cover the eyelashes and eyelids and a metallic lid speculum to hold the eyelids open. However, conventional draping does not completely cover the eyelashes and eyelids at the medial and lateral angles of the eye, and meibomian secretions can enter the surgical field from gaps between the adhesive drape and eyelids.
Task is to design a simple and reliable draping system using a new lid speculum, which will take care of all these issues.
2. Smartphone Corneal Topography : The principle of conventional corneal topography in Ophthalmology is based on a very simple concept: Placido rings based reflections from the anterior surface of the eye. A series of concentric lighted rings are projected onto the cornea, and capturing images of the reflections of these rings allows to study the shape and symmetry of the anterior corneal surface. This principle has been utilized for corneal topography devices since its inception 30 years back, and modern topography machines made today also utilize the same principle. However, corneal topography machines are all quite costly, and also very bulky devices.
With the emergence of high quality telephoto smartphone cameras, smartphones can be utilized to serve as the cameras for capturing the placido reflections from the corneal surface. Then all that would be needed, would be an adapter which can attach around the smartphone camera which can project the concentric lighted rings onto the cornea. This device would have the potential to serve as a very basic and cost effective screening corneal topographer. Of course, the aim is not to replace the conventional topographer, but a screening smartphone device would have numerous advantages.
Ideally, all young children who are detected with high cylindrical glasses numbers (astigmatism) may be at risk to develop a potentially blinding eye condition called "Keratoconus". In the early stages, the only way by which this condition can be picked up is by Corneal Topography. So it is important to screen such children with topography. Many children are undiagnosed of this condition until very late, when corneal transplant is the only option left. Having a smartphone screening topography tool can allow ophthalmologists to screen the eyes using this device, and if needed can refer the child for further testing. The purpose of creating this device would be to serve as a quick, handy and easy to use screening corneal topographer to check the symmetry and shape of the cornea, and to know whether to refer the patient for a proper topography test or not. As per our understanding, the potential for such a device would be huge in the field of ophthalmology.
3. Low visual aids for Age related macular degeneration :
Age-related macular degeneration (ARMD) accounts for 8.7% of the total blindness globally, and is the third common cause of visual impairment.Loss of vision results in the advanced form of the disease where the patients develop a central scotoma impairing the ability to read and identify faces .
Low visual aids for these patients need to serve 2 purpose - image magnification and image relocation - to shift the image away from the area of the scotoma .
Patients would first undergo a low vision (LV) assessments, including identification of preferred retinal locus (PRL). Prisms need to be added to prescription glasses to produce image relocation to the presumed - preferred retinal locus .
Fresnel prisms are often prescribed for magnification and expanding the field of vision in low vision patients . These prisms are made of optical polyvinyl chloride (PVC) and this material increases chromatic dispersion and produces a loss of contrast.

4. Portable DIY Slit Lamp :
Slit lamp evaluation is most important part of occular examination .
It helps to evaluate layers of cornea and lens and magnification of ocular structures.
Taking slit lamp regular ones are very heavy and poratability is difficult and costlier.
The task is the design of the slit lamp which can be powered using the mobile itself.
