[4] A study also found that CLE is even more effective than laser peripheral iridotomy in patients with angle closure glaucoma.
[8] Under topical anesthesia, through a 2.2 mm corneal incision, the lens nucleus and cortex are removed by irrigation and aspiration technique using a phaco machine.
However, modern surgical techniques and advanced lens technology have significantly reduced the likelihood of this and other complications.
As opposed to the more commonly performed cataract treatment, the idea of removing the lens exclusively for refractive purposes first emerged in the 18th century.
[13] The first systematic work on clear lens extraction was carried out by Polish ophthalmologist Vincenz Fukala in Vienna.
Fucala advised clear lens extraction in young high myopic (−13 diopters or more) patients with poor vision and inability to work.
