Abstract :
The most frequent preventable cause of
blindness worldwide is cataracts. Manual Small Incision
Cataract Surgery (MSICS) is still very much in use, even
though cataract surgery is always changing. The
resurgence of MSICS can be attributed to its low cost and
safety, as it primarily uses easily sterilizable equipments
and does not require sophisticated technology. This study
aims to assess corneal astigmatism and manual sutureless
(MSICS) cataract surgery after a month of follow-up.
Forty individuals with cataract diagnoses were enrolled in
this prospective study. During the procedure, a posterior
chamber intraocular lens (IOL) implantation was done in
addition to a superior manual minor incision under local
anesthesia. The findings indicated that 15% or so of the
patients experienced astigmatism following surgery. Also
the findings revealed that sphere and cylinder refraction
was significantly influenced by surgery. The means of
sphere refraction before and after surgery were 3.93±6.37
and 0.93±0.98 D, while the corresponding means for
cylinder refraction were 1.37±1.08 and 1.94±1.18 D. The
results showed that means preoperative and postoperative
Keratometry of cornea (K1) were 43.09±1.21 and
43.37±1.42 mm, while the corresponding means of
Keratometry (K2) were 43.97±1.35 and 44.49±1.59 mm.
The study concluded that the length of the superior
incision (6.0 mm) may have contributed to the higher mean
SIA than reported in other studies. However, more
research is required to determine the impact of incision
size on surgically produced astigmatism.
