Purpose: The aim of this study was to improve cosmesis in patients with corneal opacity (CO) using newer organic micronized pigments. Methods: Settings: Tertiary Care eye center, Design: Retrospective study. Inclusion criteria: Patients with unsightly corneal scars not suitable for keratoplasty, eccentric corneal opacity not requiring keratoplasty, or lenticular opacity/anterior or posterior capsular opacities in non-seeing eyes. Micronized organic pigment was used for keratopigmentation by the intrastromal pocket technique (ISPT) in deep corneal opacities and lenticular opacities, whereas the intrastromal needle puncture technique (ISNT) was used in superficial opacities or corneoiridic scars. The records of 463 patients were reviewed and analyzed for the duration of the past 7 years. Results: Two hundred and ninety-three (63.2%) patients underwent ISNT, eight underwent combined technique, and the rest underwent ISPT. The postoperative follow-up period showed more watering and redness in the needle puncture technique (p > 0.001), which resolved in 70.4% of patients by the end of 4 weeks. Repeat procedures were required in 5.3% of the patients with ISNT. The patient's satisfaction grading showed excellent levels in 375 (80.9%) patients, 45 (9.7%) had good satisfaction levels, and the rest had average satisfaction levels. Conclusion: Intrastromal keratopigmentation is a boon for unsightly corneal scars and gives respite to the patients from the social stigma. [ABSTRACT FROM AUTHOR]

Objectives: Clear corneal incision (CCI) architecture in modern microincision cataract surgery (MICS) plays an undeniable role in postoperative refraction. The goal of this study was to evaluate the effect of hinge incision prior to two-step CCI on postoperative refractive astigmatism after cataract surgery and to demonstrate the schematic presentation of these postoperative astigmatic changes via double-angle polar plots. Methods: This study involved a consecutive case series of patients who had MICS. The first incision was performed as a two-step CCI, whereas the second was made as a hinge incision prior to 2-step CCI. The preoperative corneal and postoperative refractive astigmatism and surgically induced astigmatism (SIA) were calculated by vectorial analysis. Hotelling's T2 test was performed to compare the centroid values of preoperative and postoperative corneal astigmatism. Results: A total of 63 eyes from 57 subjects were evaluated. Group I consisted of 27 eyes with the two-step CCI, and Group II included 36 eyes with the hinge incision prior to two-step CCI. No significant difference was found between the groups in terms of age, sex, axial length, keratometry readings, implanted intraocular lens power, and postoperative spherical equivalent. The centroids of corneal astigmatism postoperatively increased to 0.21 D at 87.6°±0.61 with no significance in Group I (p=0.525) and to 0.70 D at 90.6°±0.47 with significance in Group II (p=0.032). The difference in postoperative centroids between the two groups was also significantly different (p=0.043). Finally, the centroids of SIA were 0.12 D at 85.5°±0.50 and 0.22 D at 91.1°±0.49 for Group I and Group II, respectively, with no significance. Conclusion: A hinge incision did not have an unfavorable effect on postoperative refractive astigmatism; therefore, it may be preferred for controlled entrance to the anterior chamber.
