NEW BRUNSWICK, N.J.—Johnson & Johnson (NYSE: JNJ) moved to strengthen its eye health product portfolio on Friday with a $4.325 billion deal to acquire Abbott Medical Optics (AMO), a wholly-owned subsidiary of Abbott Laboratories.

AMO reported sales of $1.1 billion in 2015. The acquisition will include ophthalmic products in three business segments: cataract surgery, laser refractive surgery and consumer eye health.

"Eye health is one of the largest, fastest-growing and most underserved segments in health care today,” said Ashley McEvoy, a company group chairman with responsibility for J&J’s Vision Care Companies. “With the acquisition of Abbott Medical Optics’ strong and differentiated surgical ophthalmic portfolio, coupled with our world-leading Acuvue contact lens business, we will become a more broad-based leader in vision care. Importantly, with this acquisition we will enter cataract surgery—one of the most commonly performed surgeries and the number one cause of preventable blindness.”

AMO, a global leader in ophthalmic surgery, is known for world-class intraocular lenses used in cataract surgery. The World Health Organization estimates that approximately 20 million people are blind from age-related cataracts and that there are at least 100 million eyes with compromised visual acuity caused by cataracts. These numbers are steadily rising due to population growth and increasing life expectancy.

In addition to the cataract business, AMO has advanced laser vision (LASIK) technologies designed to enhance surgeon productivity and correct near sightedness, far sightedness and astigmatism. The acquisition also includes AMO’s consumer eye health products—over-the-counter drops for dry eye, as well as multipurpose solutions and hydrogen peroxide cleaning systems for patients who wear contact lenses.

In its statement, J&J reported that it expects the transaction to close in the first quarter of 2017, and it “would be modestly accretive immediately to adjusted earnings per share.”
