STUDY

• A prospective, non randomised study
• 53 eyes of 43 patients
• Evaluate the effect of limbal relaxing incisions
  on reducing astigmatism following cataract
  surgery.
• Minimum duration
• - 2 month after SICS or Phaco
• - 3 months after suture removal in
• conventional type

3
MATERIAL AND METHODS

• Epidemiological data and a complete general
  ophthalmic examination
• Corneal Topography and keratometry
• Pachymetry at the site of relaxing incision to be
  performed.
• The patients were assigned to five groups
• - Group I gt4 D
• - Group II 3-4 D
• - Group III 2-3 D
• - Group IV 1-2 D
• - Group V lt1 D

4
EXCLUSION CRITERIA

• Complicated pseudophakia
• Irregular corneal astigmatism, Keratoconus or
  keratoconus suspects
• Current uveitis and Glaucoma
• Pannus, pterygium and marked corneal scarring
• Any posterior segment pathology
• Follow up less than 3 month

5
GILLS NOMOGRAM
For astigmatism of gt 4.0D, LRI should be
combined with CRI to attain adequate correction
6
OBSERVATION AND RESULTS
MEAN CORRECTED ASTIGMATISM

• Spherical equivalent- No significant change
• No regression of astigmatism during the study

7
POST LRI ( at 3 Months) CHANGES IN ASTIGMATISM AT
DIFFERENT TIME INTERVALS
8
COMPARISON OF UCVA AND BSCVA (PRE AND POST LRI)
9
IMPROVEMENT IN VISUAL ACUITY LINES AFTER LRI

• No lines of UCVA or BSCVA lost and little
• overcorrection.

• No serious complications

LIMBAL RELAXING INCISION

• Relatively simple procedure to perform
• Intraoperatively and postoperatively
• coupling effect is 11 - no adjustments in IOL
  power calculation
• Lesser tendency to induce irregular astigmatism
• less postoperative glare and patient discomfort
• fastest healing
• preserves the original optical quality of the
  cornea - being a limbal procedure
• Cost effective
