[Clinical observation of foldable intraocular lens implantation by a small incision].
OBJECTIVE
To investigate a method of cataract operation capable of recovering normal visual acuity rapidly at early postoperative stage.


METHODS
131 eyes with senile cataract were divided into 3 groups: phacoemulsification with silicone foldable intraocular lens (IOL) implantation, phacoemulsification with one-piece IOL implantation and extracapsular cataract extraction with one-piece IOL implantation groups; the incision was 3.5 mm sutureless, 6.5 mm scleral tunnel incision and 11 mm limbal incision, respectively.


RESULTS
3 days after the operations, the average uncorrected visual acuity was 1.04, 0.51 and 0.46 and the proportion of normal visual acuity was 62.75%, 12.50% and 8.93% separately in the 3 groups. The average visual acuity and the proportion of normal visual acuity in 3.5 mm incision group was significantly higher than that of the other groups (P < 0.05).


CONCLUSIONS
The phacoemulsification with foldable IOL implantation through a 3.5 mm sutureless incision can make good visual acuity rehabilitation at early postoperative stage.
