Abstract Details

Purpose:

To evaluate the optimum time for stabilization of postoperative refractive errors following phacoemulsification cataract surgery with 3.5 mm clear corneal incisions.

Setting:

Kerman University of Medical Sciences Shafa Medical c Center

Methods:

In a longitudinal study (April 2012-March 2013), 81 eyes with Phacoemulsification were studied. Before surgery keratometry was done with Javal keratometer. Phacoemulsification was done through 3.2 mm corneal incisions. Incisions were extended to 3.5mm and foldable IOL was implanted in the capsular bag. The incisions were not sutured. Eye examination was done in postoperative day 1,3 ,7,14,21,28,35, then every 2weeks until stabilization of refraction. If refraction (spherical equivalent (SE), astigmatism amount and astigmatism axis) was not changed in 3 consecutive examinations, the follow up was complete. In the last exam keratometry was done. Data were analyzed with SPSS.

Results:

The age of patients was 32-83(61.35±10.9)years. Preoperative mean keratometry was 40.50-49.75(44.9±1.85)D. Preoperative kertometric astigmatism was0-4.5D(0.99±1.10). 72 eyes(88.9%) were operated through temporal incisions. Final postop refractive astigmatism was 1.14±0.96D; spherical equivalent 0.93±0.95D and Surgical induced astigmatism 0.44 ±1.02D (P<0.05). In final exam mean KR was 45.34±1.8; this shows about 0.5D steepening(P<0.05). Keratometric astigmatism was 0.85±0.72D(P>0.05). Stabilization of refraction (SE,astigmatism and axis) happened 11.46±11.40(3-75)days postoperatively; 10.18±11.34 and 11.33±11.77days about astigmatism and astigmatism axis. In about 99% stabilization of refraction happened 5 weeks after surgery. One month after surgery, in 98.6% of temporal and 77.8% of superior incisions, the refraction was stable(P>0.05).

Conclusions:

One month after phacoemulsification with 3.5mm corneal incisions the refraction will be stable in about all cases.
