Maqeba a entsoeng mofuteng ona oa ho buuoa a nyenyane, a ka tlaase ho 3mm, 'me ha a hloke lesela, ho fokotsa kotsi ea tšoaetso ea maqeba le astigmatism ea cornea. Hase feela hore nako ea ts'ebetso e khuts'oane, nako ea ho hlaphoheloa e boetse e khutšoanyane, bakuli ba ka hlaphoheloa pono ka nako e khutšoanyane ka mor'a ts'ebetso.
3. Femtosecond laser e thusitse ho ntšoa ha cataract
Tšireletseho ea ho buuoa le ho nepahala ha phekolo ea laser ho tiisitsoe.
4. Ho kenngoa ha lense ea intraocular
Lense ea maiketsetso e entsoeng ka polymer e phahameng e kenngoa ka leihlong ho tsosolosa pono.
