title: Early rehabilitation after small incision cataract surgery.
abstract: BACKGROUND
  The use of smaller cataract incision is thought to induce less astigmatism, resulting in a more stable refraction and more stable wound.
  
  
  METHODS
  We have analyzed the early astigmatic changes and rehabilitation in 20 eyes of 16 patients operated with advanced phacoemulsification techniques. The patients operated with small-incision surgery (incision 4.0 mm) were compared to those with large-incision surgery (incision 7.5 mm). Keratometric values and visual acuity data were evaluated up to 6 months postoperatively.
  
  
  RESULTS
  Less initial induced astigmatism was demonstrated at day 7 postoperatively with a 4.0-millimeter incision (0.1 +/- 0.53 D) compared with a 7.5-millimeter incision (1.90 +/- 1.97). Similar but not statistically significant changes were seen at days 1 and 30 postoperatively. Visual rehabilitation was also faster in the small-incision group and 70% of the eyes gave uncorrected visual acuity of 20/40 or better in this group as early as the first postoperative day. Only 11% of the eyes showed that uncorrected visual acuity after large-incision surgery at first postoperative day.
  
  
  CONCLUSIONS
  The low amount of induced cylinder, rapid stabilization of the wound, and faster visual rehabilitation confirms the advantage of small-incision cataract surgery to large-incision surgery.
