St.Vincent Anderson Regional is one of the first facilities in Indiana providing a new laser-assisted method of cataract surgery.
two physicians who currently provide this surgical procedure are Drs. Donald Perez and Ching Li, both board certified
ophthalmologists on the hospital’s medical staff.
cataract surgery uses a state-of-the-art computer-guided laser system
called LenSx. The laser replaces traditional hand-held blade cataract
surgery. It makes cataract surgery more precise, with a potentially more
predictable outcome. LenSx is the first femtosecond laser approved by
the FDA for use in cataract surgery in the United States.
cataract is a natural clouding of the eye’s lens and is the leading
cause of blindness among adults. Cataract surgery removes the cloudy
lens and inserts a transparent artificial implant.
precision cannot be matched,” Dr. Perez said. “The laser’s ability to
make the incision through multiple planes creates an opening that is
usually water-tight once the surgery is complete and an opening that is
more likely to not require stitches.”
While all human eyes share
the same basic anatomical structure, no two eyes are exactly the same.
This is why every eye must be carefully measured and mapped before
undergoing cataract surgery. During surgery, the LenSx provides a
high-resolution imaging, which allows surgeons to map the placement of
incisions. Therefore, the procedure is customized to the individual to
remove the cataract and position the implant.
Dr. Li explained,
“The LenSx laser helps soften the cloudy lens, which is removed through a
tiny incision. This decreases the ultrasound power needed for cataract
removal and puts the patient’s eye under less stress. This makes
cataract surgery a gentler procedure than ever before. Early reports
have shown the use of the laser may reduce swelling and speed recovery
Through careful measurements before and during the
surgery, the ophthalmologist can use a specialized lens that often
achieves the same optical correction as glasses or contact lenses. In
many cases, the LenSx laser also can be used to make precise shaving on
the cornea that will change the cornea’s shape and correct for
"The laser is helpful in the precise placement of
the artificial implants,” said Dr. Li. “Ideally, our patients would
prefer not having to wear glasses after cataract surgery. We cannot
guarantee that this surgery will eliminate the need for glasses, but it
has achieved that for many of our patients.”
technology is creating excitement among ophthalmologists across the
country,” Dr. Perez said. “I see merging of cataract and refractive
surgery as a paradigm shift in how state-of-the-art cataract surgery
will be performed in the next five years.”
VanOsdol said, “We do lots of cataract surgery here. With our aging
demographics, we saw this as an opportunity to bring this extremely
accurate, edge-cutting technology to patients in our community.”
