New York-based producer Isaac Solotaroff has produced a number of broadcast and theatrical documentaries. Eye Camp was adapted from his feature-length documentary Visioning Tibet, which has screened in over 30 international film festivals since 2005 and is currently being presented on PBS stations around the country through American Public Television. He is presently in production on a feature-length documentary about Dr. Naif Al-Mutawa and his comic book The 99.

"Cataracts are the leading cause of blindness in the world," explains reporter Isaac Solotaroff in this week's Rough Cut, filmed on the stunning high plains of Tibet.

In a country where much of the population lives at elevations of 15,000 feet, where solar radiation poses a high risk for cataracts, the disease has become an epidemic. Many of those afflicted with cataracts come from the poorest communities -- nomadic herders who have limited access to healthcare and face inevitable blindness without surgery.

But since 1995, an enterprising American ophthalmologist, Dr. Marc Lieberman, has been traveling to Tibet twice a year to run mobile eye camps.

Dr. Lieberman examines a patient at a clinic in rural Tibet.

A deeply spiritual man, Lieberman was inspired by the Dalai Lama to pursue his medical mission. Although his work is often made difficult by the political tensions of Tibetan life under Chinese rule, the primary goal of his nonprofit Tibet Vision Project is to train the Tibetan medical community to do the cataract surgeries themselves. (You can read more about Lieberman's experiences in Tibet in his interview.)

Filmmaker Isaac Solotaroff, who produced the recent FRONTLINE/World broadcast story about the controversial Arab comic book The 99, began documenting Lieberman's work in 2000. His feature-length documentary "Visioning Tibet" has been playing in film festivals since 2005. In his Rough Cut version for us, Solotaroff updates his film, focusing on one of Lieberman's trips to a remote clinic.

Accompanied by his colleague Dr. Melvyn "Yogi" Bert, Lieberman makes the familiar but arduous journey from San Francisco to Kathmandu, then on to Lhasa in Tibet, where they meet up with other medical practitioners. "It takes us five days to get to Lhasa," Lieberman explains, with the added stress of transporting medical supplies. And that's just the start. Next comes two days on the road in the back of a four-wheel drive, navigating potholes and broken bridges to reach the northern Tibet town of Sok Xian, where the weeklong eye camp will commence.

With advance news of the team's arrival, hundreds of Tibetans have descended on the town, hoping to be treated. One elderly herder named Lhasang, has camped there for a week with his entire family.

"My four children," he says, pointing them out one by one, "They are great! I am very unhappy when I can't see them and very excited about tomorrow."

But Lieberman's goodwill mission gets off to a rocky start. Since his last visit, the new medical building earmarked for surgeries has been turned into an impromptu hotel for local medical staff and the facilities have been neglected.

"The operating room looks like something out of a penal colony on Devil's Island," Lieberman tells Solotaroff, and threatens to head straight back to Lhasa.

Eventually, the Chinese and Tibetan officials clear the way for Lieberman to deliver the quality medical care he insists on for his impoverished patients. His team screens 300 patients and finds that about a third can be helped by cataract surgery. Working continual 14-hour shifts, American and Tibetan surgeons will restore the vision of 108 people before the week is out. They've treated thousands of patients since the eye camps started more than a decade ago.

Solotaroff's journey with the doctors captures many delightful moments, particularly among the Tibetan families who arrive at the camp full of anticipation and filled with gratitude when the doctors restore their sight.

"May you live for a thousand years!" declares one man as the camp is wrapping up and he's given a flashy new pair of sunglasses to protect his reclaimed vision. The Western doctors return the adulation by honoring the Tibetans who work alongside them. "Her skills are superb," Lieberman says congratulating Dr. Zheng Gui Ying, one of his proteges. "She can now do a perfect cataract operation in 15 minutes. And she trains other surgeons."

Lieberman's aim, after all, is to ultimately work himself out of a job.
