The newly-discovered eye medications, human embryonic stem cells, have created striking changes in the vision of two legally blind women. After getting injections of the said cells, the two patients experienced some improvements after losing their sight due to a fatal eye disease.

Dr. Steven Schwartz, ophthalmologist from UCLA's Jules Stein Eye Institute, was extremely excited for the complete effect of the cells. He, however, did not claim that the team had discovered an ultimate cure for blindness. The usage of human embryonic cells indicates a major step towards regenerative medicines.

The study of these miraculous cells has been published in "The Lancet."

For every patient, embryonic stem cells were injected into the retinal tissue. Before the procedure, the patient will be asked to take anti-rejection drugs within a short time in order for the eyes not to reject the strange tissue.

The 78-year-old Sue Freeman couldn't go out for a walk or shopping due to a macular degeneration. She cannot cook and pour a glass of water without spills. But after the surgery, Freeman was already able to do the things she couldn't do before.

Now, she can go out on her own, shop and cook. She can even read writings and observed a lot of other things. Her vision is slowly coming back.

Schwartz explained that the results, however, are merely preliminary. This means that the patient's vision could get bad again. To further improve or find out about the embryonic cells therapy, researchers will conduct more tests on 12 other patients from 10 different research centers worldwide.

The other woman from the study with Sue Freeman claimed that she noticed a few changes in her vision seven days after the operation. She woke up one day seeing an armoire across the bedroom. Then she began describing it with its detailed carvings. She started seeing things which she couldn't see before.

Further examination will be done to further support the effect of embryonic cells in treating the loss of sight.
