Conditions We Treat

The technology developed by Allotex’s medical engineers addresses  two central areas of vision care: presbyopia and hyperopia. The typical treatment for these conditions can be burdensome: seeing clearly requires bulky glasses, inefficient contact lenses, or invasive surgery. Allotex’s technology can change all this, providing people of all ages with the opportunity to see without difficulty. With our living lenses, ophthalmic patients of all ages can begin to see more clearly.

Presbyopia

As people age their eyes’ natural lenses thicken and become stiff, making it difficult to see small print and other small items sharply. This condition leads to headaches, eye strain, and blurry vision. In other words, as we age, presbyopia can impair an active lifestyle. With a growing population of older adults, presbyopia affects the lives of countless people living in our community. In fact, it is estimated that by 2030, nearly 2.1 billion people will suffer from presbyopia[1].

Clinical findings to date have shown that tissue addition technology can improve patients’ near vision substantially, sometimes by an average of 5 lines in emmetropic presbyopic patients, without significantly altering their preoperative distance vision. Patients have benefitted from excellent binocular UCVA at distance, intermediate (70 cm), and near (40 cm), rapid visual recovery, and minimal postoperative discomfort[2].

Hyperopia

Hyperopia is a condition of the eye where distant objects are seen clearly but near objects appear blurred. Children and adults alike can be affected by hyperopia, and experience headaches, eye strain, and blurry vision both from near and far distances.

Refractive surgery for hyperopia has been a challenge for surgeons in the last few decades. On the other hand, tissue addition technology was found to be safe and effective in the refractive treatment of hyperopia. Preliminary research indicates that this procedure improves patients’ visual acuity at near and distance with a notable degree of predictability and stability[3].
