Surgeon factor on Laser In Situ Keratomileusis in low and moderate myopia.

The purpose of this study was to evaluate the effectiveness and predictability of laser in situ keratomileusis (LASIK) procedure performed by three surgeons in low and moderate myopia. One hundred twenty nine eyes from 68 patients underwent LASIK procedure, performed by three different surgeons (X, Y, Z) using the same procedure and same instruments were reviewed. These patients are divided into two groups, group A (below – 6.00 diopters) and group B (between – 6.00 and –10.00 diopters). Patients were observed on day 1, day 7, 1st month and 3rd month. Results: The evaluation of effectiveness and predictability is based upon uncorrected visual acuity (UCVA) and spherical equivalent refraction, respectively. The variation dispersion between attempted correction and achieved correction is measured using coefficient of determination (R2). The statistical analysis shows indifferent results for the three surgeons. The conclusion was that the effectiveness and predictability of LASIK procedure performed by the three surgeons in both groups are indifferent. Hence, this study suggests that the surgeon factor does not affect the result of LASIK procedure.

Surgical outcome of phacofragmentation and phacoemulsification in senile white mature cataract.

Purpose : To compare the effectiveness and safety of phacofragmentation and phacoemulsification techniques on senile white mature cataract. Methods : Prospective, double masked, randomized study comprises 32 eyes of senile white mature cataract randomly divided into 2 groups, 16 eyes had phacofragmentation (group I) and 16 eyes had phacoemulsification (group II). The evaluated safety parameters were pupil diameter pre surgery and prior to intra ocular lens (IOL) implantation, corneal thickness and flaremeter. Nucleus delivery, uncorrected visual acuity (UCVA) and surgically induced astigmatism (SIA) were the effectiveness parameters. Follow-up were scheduled for post-operative day 1,7,15 and 30. Results : prior to the surgery there were no significant differences in age, visual acuity, corneal thickness and flaremeter between two groups. Pre surgical and prior to IOL implantation mean pupilarry diameters in both groups were not significantly different. There was no significant difference in pupillary constriction on both groups. The mean of time to deliver the nucleus was significantly longer in the group II (4.38±2.51 min) than in the group I (1.98±1.61 min). There was significant difference on UCVA (p= 0.00067) and corneal thickness (p=0.0044) only on the first post-operative day. However, there was no significant difference on further evaluations (p>0.05). There were also no significant difference on flaremeter and SIA during follow -up. Conclusion : Both phacofragmentation and phacoemulsification techniques were effective and safe for cataract surgery on senile white mature cataract. Phacofragmentation technique therefore could be an alternative small incision cataract surgery.

Surgeon factor on Laser In Situ Keratomileusis in low and moderate myopia.

This study evaluated the surgical outcome of various surgical technique in paediatric cataract implant surgery, at Jakarta Eye Center, Jakarta, Indonesia. This was a retrospective study of 57 eyes in 44 children who had primary cataract implants surgery. Three surgical techniques used were : 1. Extracapsular cataract extraction with intraocular lens implantation with intact posterior capsule which was performed on 21 eyes (group 1). 2. Extracapsular cataract extraction with intraocular lens implantation and posterior capsulorhexis (PCCC) and optic capture which was performed on 24 eyes (group 2). 3. Extracapsular cataract extraction with intra­ocular lens implantation, posterior capsulorhexis and anterior vitrectomy which was performed on 24 eyes (group 3). All patients were followed up more than one year. Our results showed that posterior capsule opacity (PCO) was developed in 20 eyes with intact capsules in group 1. All eyes had a clear visual axis in group 2. PCO developed only in one eye in group 3. In conclusion, PCCC and optic capture with or without anterior vitrectomy are effective methods in preventing PCO in infant and children.
