Purpose:The aim of this study is to describe a modified technique of vertically split-conjunctival autograft (CAG) for primary double-head pterygium and evaluate its postoperative outcome.Methods:In this retrospective, noncomparative, interventional case series, 87 eyes of 87 patients of double-head pterygium from June 2009 to June 2015 were included. They underwent vertical split CAG. A limbus-limbus orientation was not strictly maintained. Primary outcome measure was recurrence rate. Other outcome measures studied were graft retraction, Tenon's granuloma, dellen, and so on.Results:Mean age was 54.54 ± 11.51 years; M:F was 41:46. Mean follow-up was 17.28 ± 10.28 months. The only significant complication was recurrence rate of 3.45% (3 eyes out of 87). Other most common secondary outcome was graft edema, 42.52% (37 eyes out of 87) which resolved without any intervention. Other outcomes such as graft retraction (31.03%), dellen (1.15%), Tenon's granuloma (3.45%), and subconjunctival hemorrhage (36.78%) were recorded.Conclusion:Modified vertical split CAG without maintaining limbus-limbus orientation, just large enough to cover the bare scleral defect, appears to be a successful technique with lower recurrence rate in treating double-head pterygium.
Purpose:The aim of this study is to describe a modified technique of using conjunctival tissue from the pterygium itself without any rotation of graft for the primary pterygium in eyes with glaucoma filtering bleb, glaucoma suspects, and in primary double-head pterygium using fibrin glue.Methods:In this retrospective, noncomparative, interventional case series, 98 eyes of 98 patients with primary pterygium operated between July 2011 to July 2016 were included. They underwent this technique from the pterygium tissue itself. There was no rotation of this graft, and it was adhered to the bare scleral defect with fibrin glue. Histopathological analysis of pterygium tissue was done to look for morphology and thickness of this thin conjunctival tissue obtained from pterygium tissue itself. The primary outcome measure was recurrence rate. Other outcome measures studied was graft retraction and graft edema.Results:The mean age was 52 ± 10.04 years. Mean follow-up was 14 ± 8.24 months. The only significant complication was recurrence rate of 4.08% (4 eyes out of 98). The most come secondary outcome was graft edema, 52.04% (51 eyes out of 98) which resolved without any intervention. Other outcome such as graft retraction, 32.65% was also recorded.Conclusion:Conjunctival tissue from the pterygium tissue itself without actual rotation appears to be a successful technique with lower recurrence rate for treating primary pterygium in eyes with glaucoma filtering bleb, glaucoma suspects, and in primary double-head pterygium.
AIM:The aim of the study is to describe an unconventional technique of vertically split conjunctival autograft (CAG) for primary double-head pterygium and its long-term outcome.MATERIALS AND METHODS:This was a retrospective, noncomparative, interventional case series of 95 eyes of 95 patients, who underwent vertical, split CAG surgery without maintaining limbus–limbus orientation for primary double-head pterygium from January 2013 to January 2017. All patients were reviewed for recurrence in their follow-up period.RESULTS:The mean follow-up was 14.12 ± 9.42 months. The baseline characteristics included 44 males and 51 females, with a mean age of 56.24 ± 10.03 years. The only significant complication was recurrence rate of 2.10% (2 eyes out of 95). The most common secondary outcome was graft edema (36.84%, 35 eyes out of 95), which resolved without any intervention. The other outcomes such as graft retraction (12.63%), Tenon's granuloma (1.05%), and subconjunctival hemorrhage (34.73%) were also recorded.CONCLUSION:Unconventional vertical split CAG without maintaining limbus–limbus orientation has convincing results in treating double-head pterygium with lower recurrence rate.
Purpose:To compare the visual outcomes and higher order aberrations (HOAs) following wavefront optimized (WFO) laser in situ keratomileusis (LASIK) versus topography-guided customized ablation (TCAT) LASIK for myopia and myopic astigmatism.Methods:Patients who underwent femtosecond-assisted LASIK for myopic correction between August 2016 and October 2017 were included in this interventional prospective case series. The following parameters were evaluated preoperatively and at 3 months’ postoperative visit: uncorrected distance vision acuity (UDVA) and corrected distance vision acuity (CDVA), manifest refraction, and HOAs.Results:Two hundred eyes of 100 patients were included in the study. At 3 months’ postoperative visit, 92% and 90% eyes in the TCAT and WFO groups, respectively, demonstrated a UDVA of 20/20 or better (P = 0.90). A residual manifest spherical equivalent within 0.5 D was achieved in 100% and 95% of the eyes in the TCAT and WFO groups, respectively (P = 0.10). No significant difference was observed in the HOAs induced in both the groups, with slightly lower induction of trefoil and horizontal coma in the TCAT group.Conclusion:Both groups demonstrated similar refractive efficacy and predictability, with greater gain of CDVA following TCAT ablation. HOAs induced were not significantly different between the two groups. Further studies are needed to validate the superiority of one procedure over the other.
