“…A comparative study of an L-shaped incision vs. a linear incision group revealed less induced astigmatism. 5 L-shaped incisions have consistently shown better results than straight incisions in terms of postoperative astigmatism shift, induced astigmatism, pressure resistance and other complications. 5 Different types of incisions varying in length, shape and location are tried by many surgeons to obtain optimal visual rehabilitation of patients which are both beneficial and cost effective to the patients.…”

“…L-shaped incisions have been used for explantation and implantation of intraocular lens and it is found to be astigmatically neutral incision because the scar tissue tends to contract equally on both horizontal and its perpendicular axis leading to astigmatically neutral wound. Henekes and colleagues reported an L-shaped corneal tunnel incision for performing Phacoemulsification 5 . They extended the corneal tunnel wound perpendicularly for IOL (intraocular lens) implantation and found better results in terms of astigmatism.…”

Aims and objective: To compare surgically induced astigmatism(SIA) in L-shaped vs straight incision in manual small incision cataract surgery(SICS). Material method: 60 patients aged 35 years and above with uncomplicated cataract with nuclear sclerosis of any grade were included in the study who were divided into 2 groups randomly. 30 patients underwent SICS with straight scleral incision and 30 with L-shaped incision. Data was analyzed using SPSS version 15.0 statistical analysis and calculations were performed using SIA calculator version 2.1. Results: The SIA (surgically induced astigmatism) was 1.14 ± 0.44D, 0.81 ± 0.40D, 0.61 ± 0.33 D on 1st post-operative day, 4 weeks and 6 weeks respectively in straight incision group and the SIA was 0.79 ± 0.36D, 0.33 ± 0.31D, 0.15 ± 0.18D on 1st post-operative day, 4 weeks and 6 weeks respectively in L-shaped incision group. Conclusion: L-shaped incision technique induces less amount of SIA as compared to straight incision and the difference is statistically significant. Also, L-shaped incision maintains better anterior chamber stability and leads to early visual rehabilitation. In poor and developing countries where still majority of cases are being operated by manual SICS, achieving emmetropia or minimal refractive errors should be the goal.

“…Thus, in the tunnel method, it is necessary to meticulously confirm that there is no leakage at the end of the surgery. Moreover, the incision size can be reduced by using the L-shaped incision 21 for IOL removal, which prevents the likelihood of low postoperative IOP, vitreous hemorrhage, and infection.…”

In this study, we aimed to report on the early results of intrascleral intraocular lens (IOL) fixation using a hook-shaped haptic IOL (hsh-IOL). Patients and Methods: We enrolled 27 consecutive eyes of 27 patients (mean age, 74 ±11.4 years) who underwent intrascleral IOL fixation with an hsh-IOL and were followed-up for 3 months postoperatively. The reasons for surgery included insufficient capsular support, including IOL dislocation, aphakia, or dislocated crystalline lens. The haptic of the hsh-IOL was externalized from the eye using forceps, and the hook was buried in the scleral tunnel. We investigated the preoperative and 3-month postoperative corrected visual acuity (VA), intraocular pressure (IOP), corneal endothelial cell density, refractive prediction error, postoperative intraocular astigmatism, surgically induced astigmatism, and intraoperative and postoperative complications. Results: The mean postoperative corrected VA (logMAR, 0.083±0.18) was significantly better than the mean preoperative value (0.42±0.60, p=0.0007). The 3-month postoperative mean absolute prediction error was 1.00±0.96 D. The mean IOL-induced astigmatism was 0.95±0.70 D. Further, the mean postoperative corneal endothelial cell count (2036±644 cells/ mm 2 ) was significantly lower than the preoperative value (2316±527 cells/mm 2 ) (p=0.009). No patient had a 1-month postoperative IOP <5 mmHg or >25 mmHg. There were no intraoperative or vision-threatening complications, such as retinal detachment, endophthalmitis, or IOL dislocation, due to postoperative haptics misalignment. Conclusion: Intrascleral IOL fixation using hsh-IOL is an effective option for eyes with insufficient capsular support.

“…The most frequently used types of incision were the frown incision 14 and the L-shaped incision. 15 However, to our knowledge, there is only limited information available about the direct comparison between the refractive outcomes after retropupillary iris-claw IOL implantation using these modified sclerocorneal incisions.…”

Purpose To evaluate refractive outcomes after retropupillary iris-claw intraocular lens (IOL) implantation and to compare postoperative astigmatism from (1) a conventional 5.5-mm sclerocorneal incision, (2) an L-shaped scleral tunnel incision, and (3) a frown scleral tunnel incision. Methods This was a retrospective study of eyes undergoing dislocated IOL exchange for a retropupillary iris-claw IOL. Uncorrected and corrected distance visual acuity (UDVA and CDVA) and postoperative complications were evaluated until postoperative months 24. The refractive outcomes and the surgically induced astigmatism (SIA) vector were compared between groups. Results The medical records of 107 eyes from 107 patients with mean age of 65.31 ± 12.15 years were reviewed. Eyes with a frown incision showed the best UDVA, followed by those with L-shaped and conventional incisions ( P = 0.003). Eyes with an L-shaped incision or frown incision had a lower SIA than that of the conventional incision group at postoperative 6 months (mean ± standard deviation [SD] SIA, 0.86 ± 0.85 D, 0.63 ± 0.37 D, and 1.70 ± 1.27 D for frown incision, L-shaped incision, and conventional incisions, respectively; P = 0.004). Conclusion The frown incision and L-shaped incision induced a significantly smaller SIA than the conventional incisions, which was associated with better UDVA postoperatively.
