We analyzed an astigmatism and an uncorrected visual acuity in 235 eyes for 5 months following sutureless cataract surgery (167 eyes) with 5mm (Group 1), 6mm (Group 2), and 7mm (Group 3) incision lengths at 2.5mm posteriorly from the
corneoscleral
limbus, and shoelace sutured cataract surgery (68 eyes) with 7mm (Group 4) incision length at 1mm posteriorly from the corneoscleral limbus performed by one surgeon.
In three groups of sutureless cataract surgery, the surgically induced corneal astigmatisms were stable after one month postoperatively, but decreasing the length of incision substantially reduced the astigmatic changes (P>0.05), reduced the
astigmatic
swings(P>0.05), and narrowed the astigmatic ranges.
In comparison to sutured cataract surgery with 7mm incision length, sutureless cataract surgery with same incision length reduced the astigmatic changes (P<0.01), was stable early, reduced the astigmatic swings (P<0.01), and narrowed the
astigmatic
ranges.
The shorter the length of incision in sutureless cataract surgery, the higher the incidence in an uncorrected visual acuities of 20/40 or better (P>0.05). In comparison to sutured catarct surgery with 7mm incision length, sutureless cataract
surgery
with same incision length had high incidence in an uncorrected visual acuities of 20/40 or better (P<0.01).
The results indicate that smaller incision length in sutureless cataract surgery was associated with a lower surgically induced astigmatism and a better uncorrected visual acuity, and sutureless catarct surgery rather than sutured cataract
surgery
surgery was associated with a lower surgically induced astigmatism, an earlier stability, and a better uncorrected visual acuity.
